Well for me, heavy infantry means Panzergrenadier, SS division & Russian shock army.
cost = 4
att = 1 (attack at 2 in the first round of combat)
def = 2 (defend at 3 in the first round fo combat)
move = 1
Torpedo boats….I like. I think there kind of a different animal that a PT boat, which used machine guns.
actually they should have a first strike capability like subs. They rely on surprise after all.
How about torpedo boats attack 2, defend 1, and cost five, otherwise the same as PT boats in terms of movement and hits.
