 However, not to be sidelined, Hathcock returned to active duty, and along with now Major Ed Land, established the Marine Corps Sniper School at Marine Corps Base Quantico, Virginia. The results of his efforts saw the establishments of scout sniper schools at Stones Bay, Camp Lejeune, North Carolina, Camp Pendleton, California, and Marine Corps Base Kaneohe Bay in Hawaii.
