The Manned Ground Vehicles (MGV) was a family of lighter and more transportable ground vehicles developed by BAE Systems and General Dynamics as part of the U.S. Army's Future Combat Systems (FCS) program. The MGV program was intended as a successor to the Stryker of the Interim Armored Vehicle program. The MGV program was set in motion in 1999 by Army Chief of Staff Eric Shinseki. The MGVs were based on a common tracked vehicle chassis. The lead vehicle, and the only to be produced as a prototype, was the Non-Line-of-Sight Cannon. Seven other vehicle variants were to follow.
