The XM1111 Mid-Range Munition (MRM) is a 120 mm precision guided munition developed for the Rheinmetall Rh-120 120mm gun (named the M256 in the US military) used by several Western tanks. It was also intended to fulfill a requirement for Future Combat Systems (canceled) for a long-range, beyond line of sight (BLOS) tank munition.

The U.S. Army awarded two contracts in a competition to validate the requirement, one for a kinetic energy penetrator round (MRM-KE) and one for a chemical energy high-explosive anti-tank (HEAT) warhead round (MRM-CE).
In December 2007, Raytheon's CE-based concept was awarded the system-design-and-development contract to develop the round. Valued at $232.3 million, the 63-month contract covered system design and development.
The Mid-Range Munition was cancelled in 2009 along with Future Combat Systems.[1]
