M7 mine
From Wikipedia, the free encyclopedia
The M7 is a small metal cased U.S. anti-tank blast mine that was used during the Second World War. It was based on the British Hawkins grenade. 2.5 million were produced before production ceased, and although it has long since been withdrawn from U.S. service, it can be found in Angola, Burma, Cambodia, Chad, Eritrea, Ethiopia, Korea, Lebanon, Myanmar, Somalia, Thailand and Zambia.

[edit] Description
The mine has a thin olive green painted steel case, with a large hinged pressure plate. This plate transfers force onto the mines fuze. The fuze is triggered by relatively low pressures, making mine effective against trucks and cars. Additionally the fuze may be sensitive enough to make it effective as an anti-personnel mine. The mine was normally deployed inside a cloth bag or sack to prevent rocks getting trapped under the hinged lid of the mine. The mine only had a small main charge so was typically deployed in lines or rows of up to five mines to be effective against tanks.
Several variants of the mine were produced, and two chemical (the M600 and M601) and one mechanical fuze (the M603) were developed for the mine. A secondary fuze well may be fitted to the mine, for anti-handling devices.
