What OP stuff dose GUN Have We don't know about yet?
(Note: I haven't read the lore document so I may not know all the things GUN is capable off. I'm writing this post because I don't wanna go through that long doc thats still being updated lol)
Throughout the story, we've been shown the capabilities of both GUN and the Nexus. While the technological capabilities GUN has demonstrated through Emma have certainly impressed the gang, most of what we've seen so far either consists of technologies we've had since the 21st century that are primarily impressive to the gang and the rest of the Nexus because they can be accomplished without the use of magic in a larger scale by non-magical people. They aren't necessarily things that the Nexus itself would be completely incapable of reproducing through magic. They even have a form of internet and virtual world of their own using magic.
Meanwhile, we've seen the absolutely insane magical capabilities of the Nexus that GUN just can't match. They can create portals that seamlessly cross enormous distances, manipulate space itself to make areas appear larger or smaller than they actually are, create bags of holding, and even construct weapons that can literally consume the space around them like some kind of fantasy black-hole bomb.
Given the absurd and potentially reality-breaking capabilities we've seen from Nexus magic compared to the relatively mundane technological capabilities GUN has demonstrated so far, does GUN actually possess any equally insane technologies of its own that can match the Nexus in terms of sheer impressiveness and absurdity?
For example, since GUN's soldiers are either humans equipped with power armour or robotic soldiers, are their standard infantry weapons essentially Warhammer 40K-style bolters—rifles that fire rocket-propelled gernades which can be modified to have different capabilities like programmable ammunition, with computerized targeting systems capable of turning an ordinary soldier into an almost literal aimbot?
Do they possess Von Neumann probes or grey-goo-style nanomachines that can be deployed alongside generals or ordinary soldiers behind enemy lines, allowing them to manufacture infrastructure, weapons, and entire armies from local resources and then command those forces against the enemy, essentially letting a single soldier play Planetary Annihilation or Command & Conquer in real life?
Because, given the insane, reality-bending magical capabilities we've seen the Nexus wield through its mages, GUN would need some similarly absurd technological capabilities to genuinely level the playing field without relying on allied realms like Thalmins. Otherwise, can GUN really be considered an equal rival to the Nexus, as Emma claims it can be to Thalmin and the rest of the gang?
