Submarines: Can they attack other subs without a destroyer? It seems like that is not a legal attack.
You can attack them but since submarines can always submerge before any shots are fired if an enemy destroyer isn’t present the most likely result is that the defending sub will simply submerge to escape battle.
BlitzKrieg: Ok say you (German Player) have a front of 10 tanks in West Russia with 20 inf. Novosibirsk is unoccupied. The russians have a sizable force on Russia (territory) to defend your attack. So you send in 9 Tanks all your inf to attack. You win (as the G’s). Now can your 1 tank that hasn’t moved blitz through Russia (friendly zone now) and capture Novosibirsk as well?
I’m guessing that its not legal but we are trying to iron that out.
That move is illegal. You can only take enemy territories during the combat move and combat phases.
