Tactics

Hull-Down Position
This is highly recommended for US tanks, as it hides the weak hull and exposes only the extremely strong turret. To do this, find a tall (just tall enough to hide the hull; if it is too tall you can't fire through) solid object. Set yourself in a position so that your hull will be blocked by the solid object, and your turret clearly shows. This means you can freely attack any part of the enemy tank, but enemies can only attack your turret.

Flanking Enemy Tanks
This is used by highly mobile tanks against tanks with a low turret traverse rate. There are several tanks which shouldn't be flanked, because their turrets can keep up with the tank. To execute this trick, creep up on a tank (at the opposite direction from the gun). Then, fire, and then move around the tank in the same direction as the turret, at roughly the same speed. Fire when you reach a weak spot, then attack it while moving until the target is destroyed.

Using Meat Shields
Once a tank is destroyed, it won't be able to fight, but it still will be able to absorb shots. Every shot that hits a light tank can only have damage up to the tank's HP. A dead tank will not receive any damage, therefore hiding behind dead tanks can be as useful as hiding behind cover.
