Two known sections of the Federation Army are the Mobile Infantry, and the K-9 Corps, which are independent but work in conjunction with each other. The Army is transported throughout the galaxy by the Navy in various sized transports ranging from a corvette, which houses a single platoon, to regimental transports which house up to six platoons. The M.I. prefers the smaller, "speedier" corvettes because of the operational flexibility they offer. This provides the ability to conduct concurrent and/or consecutive raid-type missions over a large area of operation and on many planets or systems as opposed to larger set-piece battles or invasions in a more concentrated manner.
