German tanks are much more powerful and heavily armed. American tanks are light armored and lightly powered, but have greater speeds. American tanks should use the speed to dart between buildings and trying to flank German tanks. Aim for their tracks(wheels) at the bottom to make them stop, or aim for their main head of the tank where the main gun is at. Hitting them in the tracks, or the side, should do more damage depending on your range and such. It took me and two other tanks around 3-5 shots before the German tank exploded.
