I knew there was something to mass pineapples and stickies w. vet+officer buffs!
Was bored. Ran numbers. So with allied grit, riflemen go from 55 to 65 health per man. With Vet1, they gain received damage 0.85 which could roughly be translated to Health 1.15. 74.75 HP/man. With Vet3, they gain Health 1.1. 82.225 HP/man. Squad health 493.35. Lulz.
just remember those are vet 3 and that all goes down the drain with a terror sniper. lulz.
