In early war you on;y have the t-34's as the main battle tanks and i had a shoot out that ended when i ran out of rounds because the weak gun and the armor makes it hard to destroy other t-34's.
do a search.
i forget who put it up, but there was a very nice one with the weak spots(where you want to aim) marked very very nicely.
i read a couple of your farther down too......back off the cheaqting thing dude.....you're gonna get yerself in twouble.........
