tanks. yes i know there expensive but then again i have an armored Doctrine. 2 tanks a turn will usually do it against the Italians. if you defend well in Egypt then your doing well. if not you can still slow them down a lot.
We have a house rule where the allies can only produce minor industries in foreign soil. I believe someone else has mentioned this as well. We also don’t give the Russians the 2 free infantry every round when at war. The game is much more balanced with these rules in place. Without these rules there is no way the axis can win against a good player as the allies.
