Tank single activation comparison
Claim: "...basically every other Main Battle tank can (with luck) kill another tank with ONLY its main battle cannon.
The Hammerhead is very much unable to do that on many/most tanks."
Primary Goal: Test tanks from each faction against 3 static targets (light, mid, heavy) to determine which ones can destroy that tank with a single activation from main weapon.
Additional Goal: "...single activation from ALL weapons"
Assumptions:
Must have a single ranged weapon at STR 11 or above capable of AP-3.
Must be 200pts or less.
Must be a non-Aircraft vehicle/monster.
No bonuses from army rules, detachments, or stratagems. Only abilities that are on the data card, and assumes those abilities will activate (Heavy, re-roll options, etc). No Firing Deck. Firing from half distance. No cover. Attacker did not move.
Targets: Light "Goliath Rock Grinder" (T10/W10/3+), Mid "Leman Russ" (T11/W13/2+), Heavy "Tyrannofex" (T12/W16/2+)
Exceptions:
AI, Custodes, EC, Sisters, and Knights did not meet the criteria.
Leauges of Votaan, Adeptus Mechanicus, Orks and GSC have units with multiple models.
Space Marines have a lot of options. I settled on Gladiator Lancer over the Vindicator.
Guard has a lot of options. I settled on the Leman Russ Vanquisher.
Results:
Single Cannon Only
#1 Tyrannofex / 200pts / 32.17% Chance of Slaying avg'd across all 3 options
#2 Gladiator Lancer / 160pts / 26.77% Chance of Slaying avg'd across all 3 options
#3 CSM Vindicator / 185pts / 19.4% Chance of Slaying avg'd across all 3 options
All Weapons
#1 Leman Russ Vanquisher 145pts / 50.9% Chance of Slaying avg'd across all 3 options
#2 Hammerhead: Railgun 145pts / 36.7% Chance of Slaying avg'd across all 3 options
#3 Tyrannofex 200pts / 33.47% Chance of Slaying avg'd across all 3 options
Conclusion:
Leman Russ and Hammerhead are solid anti-tank tanks for the points.
Space Marines have the best stuff.
