United States Marine Corps Warfighting Laboratory

The United States Marine Corps Warfighting Laboratory (MCWL) was established in 1995, at Marine Corps Base Quantico, Virginia. The organization was originally known as the Commandant's Warfighting Laboratory. The battle lab is part of Combat Development and Integration—under Headquarters, United States Marine Corps—and its stated purpose is to improve current and future naval expeditionary warfare capabilities across the spectrum of conflict for current and future operating forces.

The organization is in charge of various aspects of advanced techniques and technology in the United States Marine Corps, and is also responsible for overseeing the Urban Warrior program.
