The Light Tank is a fast tank of the Allies. It is very useful for quickly attacking weakly armored vehicles such as artillery, V2s and mobile flaks. It is not effective against buildings or infantry, and has relatively little armour for a tank.
It is easily countered by rocket soldiers, and fares badly against other tanks - one medium tank is an exact match for two light tanks fighting side by side, while costing mere 150 credits more than one of them.
The light tank's speed and strength against light armor makes it the primary way to counter mobile flak at the early game, where few other options are available.
Thanks to its fast movement speed, the light tank can be used to quickly flank enemies and take out unprotected artillery, V2s, and other unprotected lightly armored vehicles. It is also useful for harassing unprotected ore trucks.
