Contributor: C. Peter Chenww2dbaseThe M3 submachine gun was designed by George Hyde in 1942, and they entered American military service on 12 Dec 1942, aiming to replace the Thompson submachine gun. Designed during war time, Hyde focused, and succeeded, in achieving a design that would be simple and cheap to produce. Between 1942 and 1945, 600,000 M3 submachine guns were manufactured.
The M3 submachine guns fired in automatic mode only. They were operated by blowback and fired from an open bolt. When American soldiers received the weapons, they nicknamed them "grease guns" as the weapons looked like the common mechanic's tool by the same name.
After the WW2, M3 submachine guns, along with the M3A1 variant designed in 1944, remained in service. They were officially retired in 1957 after an additional 80,000 units were made since 1945, but in actuality they continued to serve long after the official retirement. In the early 1990s, during the Desert Storm conflict, US Army 19th Engineering Battalion troops were equipped with M3A1 submachine guns. They were also used during the Chinese Civil War, Korean War, Vietnam War, and others.
