Modern Day Marine is co-sponsored by Marine Corps Base, Quantico, the Exposition’s home base. MCB Quantico, home to the Combat Development Command and the Marine Corps Systems Command, is responsible for setting requirements, developing equipment and systems and purchasing the equipment and systems that the Marine Corps will rely on in the years to come. These vital and unique functions play a large part in positioning Modern Day Marine as the premier military equipment, systems, services, and technology exposition.
