i tried something yesterday,
w/ 12 ipcs - 1 sub, bank 4
w/ 44 ipcs - i purchased 8 art, 4 inf.
It’s a nice little stack and the arty turns my inf into supermen. This is a sweet buffer (which hurts to lose).
Anyway, the next turn i purchased armor.
The next turn i had a nasty little force sitting in Poland looking across E. Poland at Russia, smacking its lips 🙂
