The Trade Federation's Droid Army employed the Armored Assault Tank, and it was subsequently utilized by the Confederacy of Independent Systems' Droid Army.
Vehicles of war, known as tanks, were armored and operated on the front lines, typically wielding sizable or heavy weapons. They were a common sight in many ground-based armies, where they primarily supported or initiated offensive maneuvers. Some hovertanks used repulsorlifts for movement, while others moved via caterpillar tracks, and still others were walkers. The All Terrain Tactical Enforcer was regarded as the main battle tank within the Grand Army of the Republic.
