The Future Combat Systems Manned Ground Vehicles (MGV) was a family of lighter and more transportable ground vehicles developed by BAE Systems Inc and General Dynamics as part of the United States Army's Future Combat Systems (FCS) program. The ground vehicles were to be based on a common tracked vehicle chassis. The MGV program was superseded by the Ground Combat Vehicle which has also been cancelled.

In May 2000 DARPA awarded four contracts to four industry teams to develop Future Combat Systems designs and in March 2002, the Army chose Boeing and Science Applications International Corporation (SAIC) to serve as the "lead systems integrators" to oversee the development and eventual production of the FCS’ 18 systems. In October 2002 United Defense (UD) and Boeing/SAIC signed a memorandum of understanding to bring the Objective Force Non-Line-of-Sight Cannon under the FCS umbrella.

In May 2003 the Defense Acquisition Board (DAB) approved the FCS’ next acquisition phase and in August 2004 Boeing and SAIC awarded contracts to 21 companies to design and build its various platforms and hardware and software.

In 2005 the army relented on the vehicle's requirement for roll-off C-130 transportability. Relaxing the C-130 requirement to allow vehicles to be transported in a stripped down configuration allowed the weight cap to be increased from 18 tons per vehicle, to 24 tons.

The Department of Defense announced budget cuts in April 2009, which resulted in the cancellation of the FCS Manned Ground Vehicles family. The Army issued a stop-work order for MGV and NLOS-C efforts in June. In July the army terminated the MGV, but not the NLOS-C. In the news release the army said cancelation would "negatively impact" NLOS-C development but said it was seeking a "viable path forward" for the NLOS-C.

The DoD determined that the proposed FCS vehicle designs would not provide sufficient protection against IEDs.

The Army planned to restart from the beginning on manned ground vehicles. The program's heavier successor, the Ground Combat Vehicle, was cancelled in 2014.
