Heavily armored and loaded with powerful guns, as a heavy tank you're a force to be reckoned with.
Medium tanks are incredibly varied in their armor, speed, and firepower. Tailor your strategy to individual tank models and you'll find yourself taking on different roles from scouting, support or even front line attacks.
Light tanks are the eyes and ears of the team. Use your superior maneuverability to spot the enemy, radio back to your team, and duck back quickly under cover before your opponents even know what happened.
