Mk 5 mine

The Mk 5 or Mine G.S. 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.

mechanism
Pressure activated, shear-pin fuze (350 pounds (160 kg) of pressure)

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.

gollark: At present, there is a significant performance hit.
gollark: (Indices with imaginary parts make it imagine data instead)
gollark: All Macron integers are 160-bit complex numbers so proper float support is good.
gollark: Lists are also implicitly circular.
gollark: In Macron, if you use a noninteger address, it mixes the two adjacent items.
