The big American medium with the autoloader is quite powerful and shoots fast so it’s important to hit it strong and quick. The hit zones are evenly spread out so you have quite a chance from any side as long as you know where to shoot.
The front is strong, but remember to shoot the left “eye” on the turret where the commander is or the middle of the hull (but be precise) where you’ll hit the driver if you angle it right.
The sides, as with all Americans, are where the money shots are. Go for the middle of the turret or the front and the back of the tracks to hit the crew, the ammo rack or the engine in that order.
The back is has the engine sitting between the tracks.
The ammo rack is located on the front of the sides of the hull, behind the tracks.
