The APC was meant to ferry supporting troops along with tanks. Their speed and maneuverability means they can rush through many base defenses intact to unload engineers, saboteurs, and thieves. Shove rocket infantry into an APC and escort your ore truck. If enemy airpower attacks, unload the APC to give them a nasty surprise. The speed of an APC makes it just as good for crushing personnel as it is for carrying them.
