I just looked again, vitality adds +35% HP, and base is 10 HP, so its 13.5.
paras give something like 12% bonus HP
and armor reduces damage taken by 10%
so you need 6.75 damage to down in 2 shots, in other words 6.8 damage.
the extra survivability makes you cross the 14 HP mark → FG42 and G41 don’t one hit down anymore because of that, but if you have a SMG or Assault rifle that deals already 8+ damage, those factors aren’t gonna influence the bullets to kill, unless we are considering damage drop off at range.
