You roll 1 Die for each unit.
So with 10 inf you will roll 10 dice. The reward in the big stack of inf is that you have 1 dice to roll and so more chance on a hit then if you just roll 1 die.
Do you ever skip the combat phase?
Do you ever go all the phases except the combat phase (maybe skipping the development)? Perhaps just to save up enough money to build a big army. I thought about it, but I’m afraid the other guy will build so quick that I can’t recover with new units. Thanks.
Only time I wouldn’t buy anything is so that I can drop a big navy next turn against some kind of large naval threat.
Even when I want to save for a big navy, I still buy at least enough infantry to fill my transports. Well, unless that chews up my entire bank.
I have skipped the combat phase numerous times. Sometimes it is not worth trading the land so you can preserve units. For instance, if you are reduced to Moscow you might not want to trade land so you can stock up.
