Historical Note:
The U.S. Army standardized the M42 Duster in October 1953. The increasing speed of jet aircraft made the optically sighted 40mm guns essentially useless in their intended role as anti-aircraft weapons. During the Vietnam War, however, it was found the twin 40s were devastating when used as a ground weapon against enemy formations.
