The Modular Command Post System (MCPS) is a modular tent system for mobile or temporary tactical operations centers, developed in the early-mid 1990s by the United States Army. The tents are designed to be utilised as a free-standing shelter. When used with a bootwall, it can be attached to other types of U.S. Army shelters and tactical vehicles such as variants of the HMMWV (Humvee).
