The mission of the Marine Corps Tactical Systems Support Activity (MCTSSA) is to provide 24/7 global technical support on Command, Control, Computer, Communications, Cyber, and Intelligence (C5I) systems, and to conduct testing, evaluation, engineering, and support experimentation on C5I systems and amphibious platforms in order to inform acquisition decisions and make the Fleet Marine Force (FMF) more capable. Our center of gravity is our people with their unique knowledge and dedication to duty. Our critical vulnerability is our garrison-based mission and associated opportunities for complacency.
