A.T. Mine G.S. Mark V
The Anti-Tank Mine, General Service, Mk V was a cylindrical, metal-cased United Kingdom anti-tank blast mine that entered service in 1943, during the Second World War. It was replaced in British service with the Mk 7 mine. Two versions of the mine were produced, the "Mk. V" and the "Mk. VC" with the same external dimensions. The only difference was that the Mk. VC had a half-sized explosive charge. The mine used a spider pressure plate that makes it resistant to blast overpressure. The spider rests on a central Mk 3  fuse (sometimes referred to as No.3 Mk I), which contains a spring-loaded striker held in place by a shear pin. The mine, being made largely of steel tended to rust making its activation unpredictable. It is found in Angola, Egypt, Jordan, Libya, Mozambique, Sudan, and Zimbabwe.
