Troopcarriers were a vehicle the Race's Conquest Fleet used to transport its infantry during the invasion of Tosev 3, similar to human armored personnel carriers. During the war against the Big Five, they proved vulunerable to human tanks, although they could easily destroy them as well. Following the invasion, these vehicles became vital to the Race's occupation forces. A large number were lost in more resistant regions such China and the Middle East, due to irregular warfare tactics by the natives.
