M5 mine

The M5 is a United States minimum metal plastic cased anti-tank blast mine. The mine uses either a glass or porcelain internal case with a protective outer case, made from felt impregnated with asphalt and tar paper. The mine uses a chemical fuze 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).^[1] It was used during the Second World War. The practice version, designated as M9, was also produced.^[2]
