An amphibious transport has 12 "slots". Most infantry units take up one slot, Terror drones and Brutes occupy two, regular vehicles take up three, while Apocalypse tanks, Magnetrons, Battle Fortresses, Masterminds, and MCVs take up six. Amphibious transports are very slow and lightly armored. They are particularly vulnerable to Harriers and Black Eagles, which can destroy them in two hits.
