Phuoc Tuy Province, South Vietnam. 18 February 1970. Section Commander, Corporal Joe Danyluk of Port Kembla, NSW, carrying a mortar gun [M79 40mm grenade launcher] calls a halt during a sweep through bombed-out jungle after a bloody battle in the Long Hai mountains during Operation Hamersley. His company, B Company of 8th Battalion, The Royal Australian Regiment (8RAR), together with other units of the Battalion, supported by armor, fought an estimated company of hard-core Viet Cong (VC) for a number of days in the mountains. The area was pounded by airstrikes including a raid by giant B52 bomber aircraft, naval bombardment from HMAS Vendetta, and artillery fire. Twenty-nine bodies of dead VC have been found to date.
First fielded in 1961 by the U.S. Army, the 6-pound M79 was light enough that you could carry it as a support weapon while still having a primary rifle– note CPL Danyluk’s M16 over the shoulder. In American service, it was often called the Bloop Gun or the Thumper. Meanwhile, the Ozzies referred to it as the Wombat Gun.
