MCTSSA

The Marine Corps Tactical Systems Support Activity (MCTSSA) was established in 1970 at Camp Pendleton, California, to provide technical support for the Marine Corps’ command, control, communications, computers, and intelligence (C4I) systems. Originally focused on supporting tactical data systems, MCTSSA’s mission expanded over the decades to include testing, integration, and fielding of emerging digital technologies. Throughout its history, MCTSSA has played a critical role in ensuring the operational readiness and effectiveness of Marine Corps warfighting systems. Today, it remains a vital component of the Marine Corps Systems Command, providing engineering, technical, and acquisition support for both current and future Marine Corps systems.
