 also uses the same fuze.

Description

The mines are normally olive green or sand coloured and are circular. The VS-2.2 and VS-3.6 consist of a ribbed main body containing the main charge and a large circular VS-N fuze which sits on top. The SH-55 is larger, and the circular main body is not as ribbed, it uses the same VS-N fuze as the other mines.

 is air pressure driven with pressure on the top plate of the mine forcing air into a diaphragm which exerts pressure on the striker until a retaining ball is forced into a recess. Shocks from overpressure are too short to inflate the diaphragm, this requires gradual pressure giving even greater resistance to shock.

This mine has a secondary fuze well on the bottom (where it cannot be seen) which is slightly off-set from the centre of the mine. This secondary fuze well can easily be fitted with pull-fuze which functions as an anti-handling device

Anti-handling device

An anti-handling device is an attachment to or integral part of a landmine or other munition e.g. some fuze types found in air-dropped bombs such as the M83, cluster bombs and sea mines. It is specifically designed to prevent tampering. When the protected device is disturbed it detonates, killing...

.

The main charge of the VS-2.2 is relatively small for an anti-tank mine, so it would tend to disable rather than destroy vehicles, however the VS-3.6 and SH-55 may penetrate the hull of armoured vehicles.
