Notable veterans

General Alfred M. Gray Jr., who served as the 29th Commandant of the Marine Corps from July 1, 1987, until his retirement on June 30, 1991, is considered the founder of Marine Cryptologic Support Battalion, although he never commanded the unit under that name. In 1955 then Captain Gray was tasked with forming two units, one to be assigned to Europe and the other to the Pacific area, chosen from Marines undergoing Manual Morse intercept training at the Naval Security Group (NSG) training facility at Imperial Beach, California. These two units would form the nucleus of what is known today as Marine Cryptologic Support Battalion. Upon completion of the course at Imperial Beach, the Pacific team under his command reported for duty with the NSG at Kamiseya, Japan in May 1956. In 1958 then-Captain Gray was assigned to Hawaii to form and activate the 1st Radio Company, a tactical signals intelligence (SIGINT) unit, where he would serve from September 1958 to May 1961.
