VMM-363 Red Lions Patch -Sew On Marine Medium Tiltrotor Squadron 363 the "Lucky Red Lions", was activated on June 2, 1952, at Marine Corps Air Station Santa Ana, California and was designated the Marine Helicopter Transport Squadron 363 (HMR-363). It was activated as a result of the demands of the Korean War. In 1953, the unit flew the Sikorsky HRS-1 and during this period took part in Operation Desert Rock, the first atomic test to use ground troops. Soon thereafter, the squadron became the first West Coast helicopter unit to receive the Sikorsky H-34 helicopter.

The Tiger Division was airlifted to Hill 78 in conjunction with the operation, which was viewed as the most successful Korean offensive of the war to date. The squadron was also involved with numerous operations, which increased in intensity following the Tet Offensive in early 1968. March 26, 1968 was perhaps the most disastrous day in the history of HMM-363. During a rocket attack, five squadron members were wounded and required medical evacuation. During the flight up the coast of Vietnam, the medevac aircraft lost its engine and crashed killing seven people including the commanding officer. The only survivors were the pilot and co-pilot who managed to escape before the aircraft sank in the coastal waters. On January 23, 1969, the squadron was redeployed back to California and was designated "Marine Heavy
