I'm a pro at lower level tank fights. I like the m2 medium, with to top auto-fire gun. But out of the starter tanks I like the MS1 with the 45mm cannon. Stick with other people, try to find other tanks that are off on their lonesome and team up on them. Unless you run into a me a 3 on 1 in the lower level tanks is a guaranteed win for ya. Dont play defense with tank destroyers. Just hang out behind your tanks and snipe targets with the big gun. Russia is going to be the easiest and fastest way to get to a good heavy tank. Just like during the war, most of the american tanks are kind of ****ty though there are some winners, like the M3 of the abrams, or heavies after the T1. If you want more there's a bunch of articles and stuff on the WOT forums.
