The MPB is a Polish off-route anti-tank mine. The mine consists of a cylinder mounted horizontally in a heavy steel frame, hidden from direct view of a designated target, which is used to aim the mine. It uses a Misznay Schardin effect warhead to project an armour piercing metal slug or EFP(Explosively Formed Penetrator) to an effective range of around 50 metres where it can penetrate up to 100 millimetres of armour. The mine can be triggered by either a contact fuze or a passive infra-red sensor, and is also fitted with an anti-handling device.
When used with the passive infra-red fuze, an acoustic sensor detects approaching vehicles and activates the infra-red sensor, which triggers the mine at the optimal moment as the target passes. The mine can be programmed to self-destruct after either 1, 10 or 30 days have passed.
