About the M50A1 Ontos Tank Destroyer:

Officially designated the Rifle, Multiple 106mm, Self-Propelled, M50 this unusual vehicle was dubbed Ontos, the Greek word for “thing” during its U.S. military service from 1956 until 1969. The Ontos project was originally started with the intent to develop a fast and effective reconnaissance vehicle, hence the design’s compact chassis and downright tiny turret. However, the Ontos’ purpose was quickly altered to that of an anti-tank weapon as the U.S. military began to move away from using heavier vehicles that struggled in off-road terrain. Armed with six externally mounted enormous recoilless rifles, the Ontos proved itself a reliable asset at Khe Sanh, Hue, and other battles during the Vietnam War.
