I have several house rules, trying to get someone to agree to play them is usuallly the hard part.
1. Armor can blitz into enemy territory in the non-combat phase, even if it causes a special," blitz combat phase"!
Armor that have left over movement after their combat movement only.
2." Combined Arms"; When there are Infantry+artillary+armor+air units combined in either attack or defense, all the units recieve a +1 in combat.
So, if you have only three armor, then only they and three of each other troop type gains this bonus, irregardless of how many other troop types there are.
3. Anti-Aircraft guns act as artillary too. Attack at a 3 and defend at a three. 88s’ were a bad ass gun.
