M5 mine

The M5 is a U.S. minimum metal plastic cased anti-tank blast mine. The mine uses either a glass or porcelain internal case with a protective outer case. The mine uses a chemical fuse rather than a mechanical one. It contains either 5.4 lb (2.4 kg) of TNT or 5.7 lb (2.6 kg) of tetrytol (a mixture of tetryl and TNT). It was used during the Second World War.
