Ammunition and Weapon Types in the Tethys Universe

Advancements in technology, production, and miniaturization have allowed humanity an incredible diversity of weapon systems, each with their own advantages and disadvantages. So I went through and drew an example of each, mostly to figure out the visual "design shorthand" for each classification. Been working on this for a while, and I'm SO glad it's done. (kind of, I technically ignored the Mortar and Missile weapon designs, but this was taking way too long and those are too comparable to modern weapons)

Lemme know what y'all think! Especially if I made a stupid mistake somewhere, I know in my heart of hearts that there's at least three I missed.

VMAC-30, a 30mm ETC autocannon firing combustible-casing 30x115mm shells.

The autocannon was meant to be used as an optional roof mounted MBT weapon.

The some of materials named in the APFSDS rounds are made-up, but are supposed to be High-entropy alloys

I've posted this a while ago but I redesigned it since. Very "inspired" by the VENOM-LR autocannon. Ignore the thin asf gas tube i will fix it soon.

The Model XI-IV Electromagnetic “Rifle”| The Right Arm of Imperial Control

All Questions Welcome
___________________________________________________________________

The Model XI-IV Electromagnetic "Rifle" is likely the most prolific infantry weapon in the Periphery besides the Klarksen Automatic Railgun, seeing service in every Periphery army from the smallest warlord to the great powers. It is a venerable design, being nearly 100 years old at this time, only kept in service by frequent upgrades and remodels, with the one pictured being the 4th iteration of the design.

It was originally made for the far less augmented colonial soldiers of the Eternal Empire, both to reduce costs, and because they didn't have the augments or the armor to use heavier arms from the shoulder.

Despite being made to cut costs, it still has a 1.25-8x magnification scope with low-light settings and a built in fire control system that allows it to compete with weapons like the Model XII Grenade Projecting Rifle or the M55/20 Infantry Combat System.

This allows the weapon to be effective out to the horizon and negate anything but the hardest cover.

Armor is also not much help, as light vehicles and heavy powered armor can quickly be swiss cheesed by this gun at high power settings.
This gun can maintain that power setting for a while with its large SMES mounted behind the magazine in an armored box.

Their are many different ammo types for this gun, with the most common being

1.Heavypoint: a tungsten carbide dart ( painted grey)
2.Lightpoint: a cemented steel dart ( painted green)
3.Ball: a round nosed steel round ( Painted blue)
4.Frag Ball: a round nosed sintered steel round ( Painted Red)

The rifle, in typical Imperial fashion can also shoot rifle grenades, with the most common ones being

Model XLV-G Laser guided multipurpose rocket assisted grenade
Model XLV Anti-Armor rocket assisted grenade
Model XXXIV loitering multipurpose rocket assisted grenade
Model XXII Smoke grenade
Model XXIII Multiple configuration high explosive grenade

This rifle is a model in service with the Gal'Haidan Provisional People's Defense Forces ( GHPPDF, try saying that 10 times fast).

It is carried by an Armsman, a rank from the old Imperial Jannisaries ( roughly a lance corporal in terms of seniority), marking the wielder as a member of the elite core of the Defense Forces.
Armsman Hanrick here has made a modification to her gun that is very common during the Scrambles. She has nailed a scroll bearing a prayer written out and blessed by a local Shrine Keeper to the stock as a good luck charm.

This prayer is a more general request from the heavens, rather than an appeal to a specific "sainted" individual or divinity. Icons or representations of Saints or Divinities are also common, with some people painting their guns in their entirety.

Soldiers across the social and political spectrum do this, as even some members of the militantly atheistic Tronarian Collectivist Party will allow their squadmates or locals to add prayers to their kit and guns to hopefully get that little bit of luck that will make sure that they don't get splattered by orbital gunfire.

How feasible? - Breakthrough Bunkers

Hey, so I've been thinking. How feasible is a mobile bunker? I've been thinking of adding it to my fictional army but im still thinking how practical/impractical would it be in real world and is there any examples of this? I know what you're thinking, isnt tanks already is a mobile bunker? I know, but would it be cool to have cheaper way to support defending infantry? this would be a lot cheaper than a tank since it has no engine and it has fewer components and it is towed by already existing vehicles.

Breakthrough Bunker

- Is a pre built bunker that is to be deployed on the tail of a breakthrough to enforce it. Basically a fortification on wheels. It can be deployed in 30mins and it can also be assembled again to move to a different vantage point. Typically deployed in flat terrains and roads. The size of these bunkers varies in size, there's the light bunkers which can be pulled by mules or infantry which is usually used in rougher terrains and it is armed with HMGs, LMGs, and light infantry guns. The next one is the heavy bunker it boasts a much heavier armor that is able to tank medium artillery and also armed with multiple machine guns or infantry support guns. Lastly, the medium bunkers, which combines the terrain mobility of a light bunker and the firepower of a heavy bunker, they may not be the best of both but it balances out their advantages.

Purpose:

- To accompany Motorized Breakthrough Infantry (Infantry that is used to either Defend the back of a breakthrough or support the advancement of the breakthrough) and provide them a mobile fort to aid their defense.

Advantage:

- Provides defensive infantry more firepower

- Quickly deployable when needed

- Thicker armor compared light armored vehicles

- Much less costly than armored vehicles

Disadvantages:

- Limited terrain mobility

- Weaker armor compared to static counterpart

- wont be able to retreat if the defense line falls

Edit: Additional information for my fictional army:

  • Historical era: in real history, the equivalent would be the inter-war period with a lot of countries vastly experimenting with their military.

  • Terrain: The terrain of the country is similar to west europe. (Vast open fields, occasional forest, but also small size mountains and hills)

  • Economy: it has a low tier manufacturing industry resulting in fewer armored production and limited to light armored vehicles and crude engines that are considered below average in performance.

  • Armored Doctrine: Assault Doctrine to use armored divisions of tanks and personnel carriers as a hammer to punch through enemy lines and pave a way for the infantry. (Armored divisions are often used to attempt breakthroughs and assaults)

Defensive Doctrine to reinforce defensive lines and pursue the fleeing enemy. (Armored divisions are used as a reinforcement in times of enemy assaults and pursuing enemies after failed assaults, bunkers are dropped as to not hinder the pursuit)

  • Military The army is infantry centric but values the importance of the armored cavalry. They see them as a defensive tool and a devastating tool when attacking. Although they like to modernize their equipment, budget, and manufacturing capabilities are limited for them so they often try to improvise.

Edit 2: I just realized how stupid it is that a military that is under equipped and has a weak economy is attacking other countries. But hey, italy in ww2 would be a great comparison for this. Stupid decisions happen in history and it makes story telling on blunders in a fictional history more interesting.

How would a 100% privatized war look?

Assume a free market economy in the 21st century or beyond

Basically, there is no standing army, and instead whatever part of the government is authorized to declare war puts out a contract for every conceivable part of the invasion.

Would there be one large company, army inc., that just offers all services and takes advantage of vertical integration?

Or would it be a nightmarish web of different contracts and sub-contracts.

Maybe there isn’t a standing army, but there IS a top brass, or maybe there is a standing army that’s very small and essentially ceremonial.

T-38 Nulsavi

T-38 Nulsavi

The T-38 Nulsavi was the standard service sword issued to commissioned officers of the Princetorian Republic Army, entering service between 1938 and 1958. The name "Nulsavi" means "sword" in the Princetorian language. It was developed from the traditional straight swords and sabres used in Princetoria during the 18th and 19th centuries, preserving many defining characteristics of the nation's classical swordsmithing tradition, including its straight blade profile, restrained ornamentation, and balanced effectiveness in both cutting and thrusting.

The sword measures approximately 89–92 cm in overall length, with a blade length of 61–66 cm and a grip measuring 23–25 cm. While its general silhouette resembles that of a military sabre, the T-38 features a thicker, straighter, and more robust construction. Its relatively narrow blade enhances thrusting performance while retaining effective cutting capability. The extended hilt allows the weapon to be wielded comfortably with either one or two hands, making the Nulsavi a practical close-combat weapon rather than merely a ceremonial officer's sword.

The adoption of the T-38 originated with the rise of the Vinze ideology in 1937, a nationalist movement that strongly emphasized loyalty to the state and the duty of every citizen to the nation. During this period, the government also revived the concept of Sela Norm, an ancient Princetorian warrior code centered on duty, honor, and the ideal of "dying with one's sword in hand to protect those behind." This philosophy was employed to strengthen morale and inspire determination among military officers, ultimately leading to the official introduction of the T-38 Nulsavi in 1938.

Although the T-38 served as the Army's standard officer's sword, officers were also permitted to carry traditional Nulsavi swords passed down within their families. This practice reflected the fusion of the modern military tradition with the honor, heritage, and legacy of Princetoria's historic warrior class.

In terms of design, the T-38 emphasized simplicity, durability, and discipline. Both the sword and its scabbard featured minimal ornamentation, with every component designed according to the principles of an industrialized military state that valued discipline, efficiency, and duty above artistic extravagance. As a result, the Nulsavi became more than an officer's sidearm—it evolved into a symbol of Princetoria's military ideology and national spirit during the age of war.

Reever Kennedy Class-Frigate

Reever Kennedy-class frigate

The Reever Kennedy-class frigate is a class of modern multi-role warships in service with the Coalition Naval Forces (CNF), the naval branch of the military of the United Coalition of Independent States (UCIS). Designed and built by Helion Shipyards, the class was developed in the early 2220s to replace the aging Donnager-class frigates and to expand the Coalition’s inventory of modern escort and patrol warships.

Though not the most advanced frigate design in Coalition service, the Reever Kennedy-class has proven to be a reliable and effective platform, combining long endurance, modular armament, and strong operational flexibility in a relatively compact hull.

The class was designed to fulfill the broad range of day-to-day security duties required of the Coalition Naval Forces, including trade route protection, convoy escort, anti-piracy operations, fleet screening, customs enforcement, and rapid-response patrol work in distant outer regions of Coalition-controlled star systems. Its balanced design, common missile compatibility, and modular weapons arrangement have made it one of the CNF’s principal general-purpose frigate classes.

Development

By the early 2220s, the Coalition Naval Forces faced a growing requirement for a new frigate class. The long-serving Donnager-class frigates, many of which were approaching fifty years of service, were increasingly regarded as obsolete in the face of modern sensor systems, electronic warfare, and long-range guided munitions.

At the same time, the United Coalition of Independent States continued to expand its commercial and military commitments across six star systems, placing growing pressure on the CNF to maintain a larger and more modern escort fleet for trade route security, anti-piracy patrols, and outer-system presence operations.

In 2221, the Coalition Joint Operations Staff (CJOS) formally presented the issue to the Coalition Defense Ministry (CDM), recommending the procurement of a new class of modern multi-role frigates capable of replacing the Donnager-class while remaining economical enough for large-scale production. The Defense Ministry accepted the recommendation and, with the approval of the Coalition Assembly, issued a competitive tender in 2222 for a new frigate design.

The requirement called for a modern and capable warship with strong endurance, effective anti-craft and escort capabilities, modular weapons capacity, and the ability to operate independently in distant outer regions of Coalition-controlled star systems. Following the evaluation of multiple proposals, Helion Shipyards was selected as the winning contractor in 2224 and awarded a 7.8 billion Galactic Credit (GC) contract covering the design and construction of 196 hulls, with an option for additional units.

The lead ship of the class, CNS Reever Kennedy, was laid down shortly after the contract award and entered service as the first ship of the Coalition’s new general-purpose frigate program. Production proceeded steadily through the late 2220s and into the 2230s, with the class gradually assuming the bulk of the Donnager-class’s escort, patrol, and trade-route security duties.

Strategic context

The Reever Kennedy-class was developed within the broader military and economic framework of the United Coalition of Independent States, long regarded as the most powerful major power in known space, though increasingly facing signs of gradual decline. The UCIS controls six star systems, approximately twenty-two colonized worlds, and a population of roughly 196 billion, supported by an economy of approximately 48 trillion Galactic Credits. Coalition power is rooted in trade, logistics, interstellar infrastructure, and the maintenance of common standards governing shipping, inspections, insurance, and commercial certification across much of the Orion Spur.

Despite its immense strength, the UCIS has faced growing internal challenges, particularly from bureaucratic inefficiencies, administrative fragmentation, and competing priorities across economic, political, and civilian sectors. These issues have, at times, slowed military procurement and modernization efforts, forcing the Coalition to prioritize cost-effective, reliable designs over highly specialized or cutting-edge systems.

At the same time, the UCIS operates in an increasingly competitive strategic environment. One of the most significant emerging powers is the Socialist Republic of Krasnor (SREoK), whose ambitions and rapid military expansion have drawn considerable attention. The Krasnorian military, with its massive personnel base, extensive industrial capacity, and emphasis on long-duration warfare, represents a fundamentally different model of military power compared to the Coalition’s expeditionary and trade-focused forces. While the UCIS maintains superior reach and logistical integration, Krasnor’s ability to mobilize vast resources and sustain prolonged conflict has introduced new strategic considerations for Coalition planners.

Within this context, the Coalition Naval Forces remain central to maintaining UCIS influence. Unlike many other interstellar powers, the UCIS maintains a navy designed not only for territorial defense, but also for the continuous protection of trade routes, Jump Lane infrastructure, commercial traffic, and allied systems spread across multiple star systems. Coalition doctrine emphasizes presence, rapid response, interoperability, long-range logistics, and sustained force projection, requiring a large number of dependable escort warships that can be deployed across vast areas without the cost and logistical
burden of cruiser- or destroyer-level assets.

This strategic environment heavily influenced the Reever Kennedy-class. Rather than being designed as a high-end fleet duelist, the class was built to serve as a practical, numerous, and dependable frigate capable of performing the routine but essential missions that sustain Coalition influence. In particular, the class is used to secure local and regional Jump Lanes, escort commercial shipping, protect fuel depots and orbital stations, conduct anti-piracy patrols, and respond to insurgent or raider activity before heavier Coalition fleet assets are required.

Because interstellar commerce relies upon stable Jump Lane access and the Galactic Credit clearing network administered by the Kuzong-Trük Banking Clan (KTBC), even small disruptions can produce major economic consequences. Piracy, supply-chain attacks, FFS sabotage, and geopolitical tensions all create demand for a large force of capable escort warships.

The Reever Kennedy-class was built to answer that requirement, and was ultimately deemed sufficient by the Coalition Assembly—while not heavily armed for its size, it was considered adequately equipped to fulfill its intended operational role within the broader structure of Coalition naval strategy.

Design

The Reever Kennedy-class was designed from the outset as a multi-role escort and patrol frigate, intended to fulfill a broad range of missions without excessive specialization. The class is built around a modular design philosophy and is equipped with six external mounts, allowing individual ships to carry different combinations of missile systems, cannon systems, or sensor packages depending on mission requirements.

This flexibility allows the class to be configured for trade route security, convoy escort, anti-craft defense, outer-region patrol work, electronic warfare support, or reconnaissance support without requiring major structural modification. Although compact by Coalition standards, the class is regarded as a balanced and capable warship. Its combination of endurance, modularity, and respectable firepower has made it a valuable general-purpose asset across a wide range of theaters.

Primary operational roles

In Coalition service, Reever Kennedy-class frigates are commonly employed in the following roles:

- Convoy escort
- Trade route protection
- Fleet screening
Independent patrol operations
Anti-piracy missions
- Outer-region security and presence patrols within star systems
- Point-defense and anti-craft escort duties for larger task groups
- Limited anti-ship strike missions
- Electronic warfare support and countermeasure deployment
- Sensor picket and reconnaissance support when fitted with mission-specific packages
- Customs enforcement and inspection support
- Rapid-response security missions
- Protection of orbital infrastructure, fuel depots, and logistics nodes

Characteristics

Class: Multipurpose Escort Frigate
Operator: Coalition Naval Forces (CNF)
Builder: Helion Shipyards
Length: 52.85 m
Height: 26.82 m
Beam: 13.91 m
Displacement: 3,700 tons
Crew: 41
Endurance: 180 days
Maximum acceleration: 4.5g sustained
Emergency acceleration: 6.5g under full emergency power
Maximum jump range: 127 light-years

The class is equipped with both a Jump Drive and Supercruise system, allowing it to operate across local and regional routes as well as undertake long-range deployments. Its stated acceleration figures refer to the ship’s standard powered flight performance rather than supercruise transit capability.

Under normal conditions, the Reever Kennedy-class can sustain 4.5g. Under full emergency power, acceleration can be temporarily increased to 6.5g, though prolonged operation at that level risks damage to the propulsion system.

Sensors and combat systems

The Reever Kennedy-class is equipped with an AsBi T-77X Primary Multifunction Radar, with a detection range of 310 kilometers. This is supported by Tridex MRO-2262 engagement radars, all integrated through the AngelBird combat system. Together, the suite is capable of detecting and tracking up to 48 targets simultaneously.

The class’s combat system is generally regarded as proven, reliable, and capable, even if it is no longer considered among the most advanced systems in Coalition service. While later sensor suites have surpassed it in raw performance, the Reever Kennedy’s electronics package remains fully effective for the class’s intended frontline escort, patrol, and convoy protection duties.

Armament

The Reever Kennedy-class uses a modular armament arrangement, with its most common configuration being the Type IA fit.

Type IA configuration

1 × MA-94S1 127 mm autoloading cannon
Stabilized main gun mount
Rate of fire: 20 rounds per minute
1 × 12-cell modular vertical launch system

Capable of firing a variety of guided munitions, including members of the Common Missile family used by the Coalition Naval Forces
Compatible munitions include:

-CM-1
-CM-2
-CM-4

CM-1 (Common Missile-1) short-range missiles can be quad-stacked within each cell, significantly increasing total carried missile count for point-defense roles

Primarily intended for anti-craft engagements, though capable of secondary anti-ship employment
Also compatible with Pavehawk Mod. 2 cruise missiles

2 × 9-cell vertical launch systems
May be fitted with:

CM-1 point-defense / short-range anti-craft missiles
TX-22 chaff countermeasure rounds
TX-31 radar countermeasure rounds
Electronic warfare suite

Integrated with the ship’s defensive systems and countermeasure launchers

Point-defense armament
For close-in defense, the class mounts:
5 × STINGER III 30 mm CIWS
Single-barrel mounts
Rate of fire: 5,500 rounds per minute

Each mount fitted with its own engagement radar

The STINGER III system is intended primarily for point defense against incoming missiles, strike craft, and other close-range threats. The weapon can also be used against smaller craft and lightly armored small ships. A known limitation of the system is that its independent engagement radars are susceptible to jamming, particularly in heavy electronic warfare environments.

Propulsion

Propulsion is provided by 8 × ORSIS 5 primary ion engines, powered by a single AMstar Dynamics JG-550B fusion reactor. This arrangement gives the Reever Kennedy-class a good balance of endurance, acceleration, and operational reach for a ship of its size.

The class was designed for long-duration escort and patrol missions, including operations far from major fleet bases. Its endurance and jump capability make it especially useful in outer regions of star systems, where Coalition warships may be required to remain on station for extended periods with limited support.

The ship’s Jump Drive is based on the standard Coalition implementation of the Abrahn-Rhyner Drive, the principal faster-than-light propulsion system used throughout the Orion Spur. Like all jump-capable vessels, the Reever Kennedy-class relies on established Jump Lanes for safe and efficient interstellar travel. Its Supercruise capability allows rapid transit within star systems, enabling the class to move quickly between planets, stations, logistics hubs, and patrol sectors once deployed.

Because Coalition naval doctrine depends heavily on maintaining security across major trade corridors and strategic lane junctions, the class’s jump range and endurance are considered among its most valuable operational characteristics. Reever Kennedy-class ships are frequently assigned to patrol lane-adjacent space, escort commercial traffic between high-value orbital facilities, and provide rapid-response coverage across wide intra-system distances.

Protection

Hull protection consists of 80 mm of TSH-6550 hardened steel armor applied across the ship’s hull, with additional double-layer armor fitted over critical sections. These reinforced areas include vital internal spaces such as command, propulsion, and munitions compartments, improving the class’s survivability against battle damage without significantly increasing displacement.

The armor scheme reflects the class’s intended role as an escort warship rather than a heavy line combatant. It is designed to provide useful survivability against splinters, missile fragments, secondary damage, and limited direct hits while preserving endurance, acceleration, and mission flexibility.

Service

Since entering service, the Reever Kennedy-class has become one of the CNF’s principal general-purpose frigates. As of the present, 74 ships have been completed and commissioned, with 11 additional hulls undergoing trials, and the remainder of the class still under construction or on order.

The class is most commonly encountered on trade route security patrols, convoy escort assignments, and independent anti-piracy operations, particularly in more distant or less secure outer regions of Coalition-controlled star systems. In larger formations, Reever Kennedy-class ships are frequently assigned to screening and escort roles, where their anti-craft weapons, point-defense systems, and modular countermeasure loadouts make them well suited to protecting higher-value units such as carriers, heavy transports, replenishment ships, and cruisers.

The class has also proven useful as an outer-region patrol platform, where its long endurance and flexible mission equipment allow it to perform customs enforcement, anti-raider patrols, anti-smuggling sweeps, and rapid-response security missions with limited external support.

Reever Kennedy-class ships are routinely assigned to escort fuel convoys, protect orbital infrastructure, support inspection operations near lane hubs, and reinforce anti-piracy task groups operating in less secure regions of Coalition space.

Although more advanced frigate designs are expected to emerge in the future, the Reever Kennedy-class remains a valuable and capable component of the Coalition fleet due to its reliability, versatility, and ability to be fielded in large numbers.

Assessment

The Reever Kennedy-class is generally regarded as a successful Coalition frigate because it matches the CNF’s actual strategic requirements. It was not designed to be the most powerful frigate in known space, nor to replace destroyers or cruisers in major fleet combat. Instead, it was designed to be a practical and dependable warship that could be produced in quantity and assigned to the routine but essential missions that sustain Coalition influence across the Orion Spur.

Its greatest strengths are its long endurance, modular weapons arrangement, common missile compatibility, good acceleration, ease of maintenance, relatively low operating cost, and ability to operate independently for prolonged periods. These qualities make it especially useful for convoy escort, anti-piracy patrols, and the protection of critical trade infrastructure. The class also benefits from high logistical interoperability with other Coalition vessels due to its use of standardized systems and munitions, allowing it to integrate easily into mixed task groups.

Its weaknesses are also well understood. The AngelBird combat system and AsBi T-77X radar remain capable, but they are no longer cutting-edge by Coalition standards. The STINGER III CIWS provides strong point defense, but its independent engagement radars are vulnerable to jamming in heavy electronic warfare environments. Likewise, the class’s armor, while respectable for a ship of its size, does not allow it to absorb the punishment expected of larger warships.

Additional limitations include restricted missile capacity compared to larger escorts, limited redundancy in critical systems due to its compact hull, and reduced effectiveness in high-intensity fleet engagements where more specialized or heavily armed vessels are required.

This was my first attempt at a genuine full sized warship design. And introducing 2 new major factions, This took me a very long time to put together all of this information as i’m sure you’re all aware. So i hope you enjoyed reading this. Is the design good? shit? I’d love to hear from you guys in the comments, even if it’s criticism. Thank you so much for reading.

The Butchering of Velutaria

It's finally over. The bastards will be entombed into molten crust soon enough. — High Admiral Sir Pavel A. Zhikov

The Butchering of Velutaria

The cornerstone of recent galactic events is unequivocally the Casarian bombardment of the Velutarian homeworld on October 15th 1600 PA (29 BBT). Widely known as the Butchering of Velutaria, it cemented the complete and utter victory of the Casarian Star Kingdom over the technologically superior Velutarian Technocracy.

For more than two decades, the Casarians fought a desperate war of survival against the unparalleled Velutarians. Under Regent MacKinnon, a royal-military dictatorship ensured the survival of the Starborne Realm. With the Star Kingdom's own citizens enthralled by the Velutarian cybernetics, the conflict scarred recent memory across millions of stars. However, with enduring Casarian grit, the brutal war gave rise to numerous heroes, amongst whom High Admiral Tague, Grand Marshal Garrad, High Admiral Zhikov, and the legendary High Admiral Coriton emerged as the supreme champions of war.

With helical rail cannons revolutionising High Admiral Coriton's naval doctrine, the Casarians were able to overcome the staggering Velutarian forces in the battle known as the Turning Gleam. In the subsequent offensives, High Admiral Zhikov brought the full wrath of the Star Kingdom to bear. In a masterful final encirclement, he isolated the last remaining stronghold of the Velutarians. Raised a Peer of the Astral Lion by the High King Himself and awarded the Star Kingdom's most prestigious decorations, Zhikov set the stage for the Velutarian surrender. Yet when the Velutarians rejected the Casarian proposal, only total victory remained. Thus ended MacKinnon's regency and began the reign of the 53rd Astral High King of the Casarians, Alexander IX Casarion. In both splendour and terror.

What impact would practical bullet resistant armor have on early modern warfare?

I've been playing a lot of Shogun 2 Total War: Fall Of The Samurai recently and got inspired to make my own "hermit empire meets the industrialized world" kind of setting. Fortunately, I already had a fantasy planet ready with more than enough empty spaces to add that kind of thing.

And now my previously established lore about the specific place I've chosen to be the hermit empire has resulted in some interesting developments.

One of these is armor made of lindwyrm shells. I've used these before and never specified how tough exactly they are. Now I am tempted to make them resistant against black powder weapons and I'm not entirely sure how they would affect gunpowder warfare with roughly 1850-1880 technology.

Here are the characteristics of the armor:

  1. The armor is affordable enough equip some units with it, but not so cheap as to be ubiquitous.
  2. It's also quite light and comfortable to wear. You don't need a thick cuirass. Segmented armor works just fine, as long as the rivets holding it together are up to the task and you got some padding underneath.
  3. It can only stop black powder pistol and rifle rounds. Modern smokeless powder would get through and if you shoot at the wearer with a wall gun or a swivel gun, it doesn't matter whether the armor stops the bullet, the guy will be dead from the impact alone.

Here are the consequences I got so far:

  1. Strengthening the caste system of the hermit empire. They did have guns before being forced out of isolation, but only matchlocks and wheellocks. Expensive and difficult to use, which is why having a dedicated warrior caste still worked. That bullet resistant armor would add onto that. Even with cheap flintlock muskets and socket bayonets, an army of peasant conscripts would have a harder time against the armored warrior caste.
  2. Melee becomes more important. The warrior caste would essentially use the Gå På tactic of the Swedish Caroleans, where you march through enemy fire until you can see the white in their eyes, then unload your volleys at close range and then charge. Dedicated melee infantry like pikemen would also stay viable for much longer.
  3. Lancer cavalry would remain important well into the era of breach loaders and metallic cartridges, if this armor is given to horses as well.

I am a bit worried that this would make the old warrior caste too powerful. Part of the storyline I've planned out is about the lower castes using imported weapons to rise up against their rulers. Easy to use flintlock muskets, later Minié rifles and finally breach loaders would have been the great equalizer here that allows peasant conscript armies to defeat noble warriors that have trained their entire lives.

I am not sure how effective this armor can be until it overturns this idea.

[Question] I've heard the phrase "cavalry never won a single battle during WWI" and it made me thinking, since cavalry is... well, important part of my lore. Or... was

Pretty much image sums my question. Allright. I will try to explain it. I will talk about World War i and World War II because both of these wars had cavalry and machine guns.

WWI: Trench warfare killed the horse. I'm not kidding. From what I know, horses were as useless as it was ever possible. I am NOT talking about logistics and using horses to carry things from point A to point B. And I also find it ironic that Americans made cavalry sword AFTER they made their best pistol, not before.

I know that Germans, China, Japan and Soviets used cavalry during WWII, but... literally 2 of these nations lost the war, China... China is a giant anomaly of the first half of the XX century, it doesn't count, and Soviets.... I don't think they really used cavalry, probably it was for propaganda and morale. German Reich easily managed to get many of the Cossacks on it's side, so I don't think that we can even count Cossacks as something successfull. Be honest with me, who even knows about cavalry in WWII besides history enthusiasts? It wasn't widely used. Tanks, planes, rockets, but cavalry? We don't think about horses when we're talking about WWII.

To me it seems that horses were obsolete by the end of 1915. Sadly...

---------------------------------------------

Allright. I get it. Eastern front and Orient, I get it. Thank you for explaining it all to me. Thank you.

Has anyone ever felt that no matter how much effort and dedication they put into WorldBuild, it's not enough?

Has anyone ever felt that their world-building, no matter how detailed, coherent, and good it is, isn't enough? I have, and I honestly hate feeling that way. Any advice?

For all my sci-fi world-builders, what does ground combat look like to you?

For my setting, the Orion Spur, humanity has colonized the stars, and the major factions each control multiple star systems. Space combat is a huge part of warfare, but it definitely isn’t everything. Fleets can destroy ships, blockade planets, and provide orbital support, but they can’t occupy territory. In the end, wars are still won and lost by the soldiers on the ground.

Each faction maintains its own dedicated army and atmospheric air force, equipped with conventional aircraft, VTOLs, and helicopters. Space fighters are capable of flying in an atmosphere, but they’re not optimized for it.

Escaping a planet’s gravity well still takes an enormous amount of energy, so dedicated atmospheric aircraft remain the backbone of air support during planetary campaigns.

Ground troops primarily use conventional kinetic weapons rather than energy weapons. Advances in technology have certainly improved firearms, ammunition, optics, and armor, but a high-velocity projectile is still one of the most reliable and effective ways to put a bloke 6 feet under… If it ain’t broke, don’t fix it.

A planetary invasion usually begins after the fleet establishes orbital superiority around the planet. While the fleet remains in orbit, space fighters deployed from warships act as the first leg, escorting VTOL dropships into predetermined landing zones, inserting the first wave of troops.

These landings bring in infantry, main battle tanks (MBTs), infantry fighting vehicles (IFVs), armored personnel carriers (APCs), logistics vehicles, unmanned ground vehicles (UGVs), engineers, and air defense systems to establish a secure foothold while protecting against enemy aircraft operating within the atmosphere.

Once the beachhead is secure, expeditionary airbases are established, allowing dedicated atmospheric fighters, bombers, helicopters, and attack aircraft to join the fight and provide close air support for the advancing ground forces.

The primary objectives are to capture and secure major population centers, strategic infrastructure, military installations, spaceports, and other locations that are critical to the planet’s defense. Depending on how heavily defended the world is, a campaign can last anywhere from a few weeks to several months—or even longer.

The opening phase of an invasion is often the most decisive. If the attackers can rapidly seize key objectives and disrupt the defenders’ command structure, the campaign may end relatively quickly. But if that momentum is lost, the invasion can bog down into a brutal war of attrition.

A blockaded planet isn’t necessarily a defeated one. As long as it has functioning industry, stockpiles of military equipment, ammunition, fuel, and food, it can continue resisting for months or even years. Many developed worlds are capable of manufacturing replacement vehicles, weapons, munitions, drones, and other essential war material while under siege, making them far more difficult to conquer than simply surrounding them from orbit.

Because of this, planetary invasions are among the costliest military operations imaginable in my universe. Even after achieving orbital superiority, the attacking force still has to fight through prepared defensive lines, fortified cities, and entrenched armies. Casualties can climb into the hundreds of thousands—or even millions—if the campaign turns into a prolonged stalemate.

Most of the fighting is concentrated around cities and strategically important locations, where combined arms warfare dominates the battlefield. Infantry, tanks, IFVs, artillery, drones, aircraft, engineers, logistics units, and electronic warfare assets all play their part, each supporting the others to keep the advance moving.

Special forces also have an important role, carrying out missions like seizing enemy ICBM silos, raiding command-and-control centers, gathering intelligence, sabotaging key infrastructure, designating targets for precision strikes, and eliminating high-value assets behind enemy lines.

Orbital bombardment is always an option, whether through kinetic strikes, guided missiles, or heavy naval guns. However, it is generally treated as a last resort. While orbital firepower can devastate hardened military positions and break defensive strongholds, it also carries an enormous risk of civilian casualties, infrastructure destruction, environmental damage, and long-term economic consequences.

If the goal is to occupy and govern the planet afterward rather than reduce it to rubble, commanders usually prefer precision strikes and ground operations whenever possible.

So, that’s the general idea behind warfare in my worldbuild. Space superiority is essential, but it’s only the beginning. Taking a planet is an entirely different challenge, and once boots are on the ground, the outcome depends on logistics, industry, leadership, and the ability to sustain a long campaign not just who has the biggest and coolest fleet.

I’m curious how battles work in your setting too! I’d love to hear about it. :)

[Question] How dangerous for the army the living corpses can be, if they aren't 'braindead'? The corpses, not the army

Allright. Yet another question of mine. I think you guys will remember me as a guy with stupid questions, if I continue asking.

What we have:

A fellow, who is walking, despite being somewhat.. dead. You may even call him a 'zombie'. But this fellow is not your regular zombie. He is, somewhat alive at the same time as being dead. He needs to eat and drink something, he may be rotting, but it's very slow, slower than regular corpse. Unlike the real and normal dead body, this zombie will rot to effectively disfunctional bag of flesh and bones 9-12 months since the death. it can take 2 years, in rare cases, until zombie will rot to nothing.

They can even speak! They can recognise each other, and they won't attack each other. They can't answer anything but simple questions. For example, they will answer if you ask them what colour is your eyes, but if you have heterochromia, poor undead will be so confused that he won't answer it, for... about two hours.

And these rotting trotters are capable of using simple tools! They can't aim good due to the poor sight, but they definetly can try to shoot you. They can even try to reload the weapon, but I doubt that these shamblers would actually reload their firearms if they don't have already prepared magazines for them, or if the weapon isn't loaded manually, bullet by bullet, like a revolver, or tube-fed shotgun, or rifle.

Basically they have a brain of a parrot, or a chimp, because I suppose they are somewhat similar in this way.

They don't feel pain, they can move even if they're injured.

Basically they are close to the Crossed from the Crossed series. But they are rotting, unlike the crossed, and that's the most important thing.

This virus is airborne. And it also spreads through the water. Animals are safe.

How long will it take for a modern army to get rid of those? How would army in YOUR worldbuilding project deal with these? Is this even something serious, or is it laughably easy to deal with?

My 6.5mm intermediate cartridge

So I've been thinking for a long time about a bullet that sits right in between 5.56 and 7.62 for a assult rifle and I thought maby a 6.5mm might be great but all the 6.5 out there are not compatible with a ssult rifle style platform so I designed a 6.5mm intermediate round that can be used with a 30 round mag and I used ai to make a blueprint of it and I was hopping to know what people thought of it and if any one has a idea on how to improve it.
