Ontos, officially the Rifle, Multiple 106 mm, Self-propelled, M50, was a U.S. light armored tracked anti-tank vehicle developed in the 1950s.
It mounted six 106 mm manually loaded M40 recoilless rifles as its main armament, which could be fired in rapid succession against single targets to guarantee a kill. Although the actual caliber of the main guns was 105 mm it was designated 106 mm to prevent confusion with the ammunition for the 105 mm M27 recoilless rifle, which the M40 replaced.
It was produced in limited numbers for the U.S. Marines after the U.S. Army cancelled the project. The Marines consistently reported excellent results when they used the Ontos for direct fire support against infantry in numerous battles and operations during the Vietnam War. The American stock of Ontos was largely expended towards the end of the conflict and the Ontos was removed from service in 1969.Quảng Ngãi Airfield

USS White River (LSMR-536) (later LFR-536) was a Landing Ship Medium (Rocket) (LSMR) in service with the US Navy between 1945 and 1946, 1950 and 1956, and 1965 and 1970. As a member of the LSM(R)-501-class Landing Ship Medium (Rocket), White River was designed to provide rocket fire support to US and allied amphibious operations, although in Vietnam she was generally used to bombard enemy formations and installations. She saw combat in the Korean and Vietnam Wars, making a large contribution to the latter, in which she fired tens to hundreds of thousands of rockets in support of American, South Vietnamese, and South Korean operations against the Viet Cong during ten tours of duty in Vietnam, 1966 through 1969. In Navy publications such as All Hands and the Navy Times, as well as in the recollections of crew, forward observers and spotters, and ground forces receiving her support, White River was reported to have the firepower of six destroyers or a cruiser. She could fire 250 65-pound (29 kg) rockets in a minute, plus 5-inch shells and autocannon fire, and carry a magazine of 1,500-2,000 rockets.White River was named LSMR-536 when she was launched by the Brown Shipbuilding Company in 1945 and during her Korean War service, only acquiring the name White River in 1955 after returning to the United States. She was reclassified as an Inshore Fire Support Ship (LFR) on 14 August 1968, better reflecting her fire support role in Vietnam. She was decommissioned and struck from the Naval Register in 1970 and sold for scrap that same year.White River was among the ships exposed to the toxic Agent Orange herbicide while docked at port or conducting operations in Vietnam's inland waterways, and any crew who served on White River in Vietnam can be presumed to have been exposed to toxic herbicides without further development according to the Veterans Administration.
