MPB mine

The MPB consists of a metal cylinder filled with explosives, mounted horizontally in an adjustable frame.

The mine is intended to be hidden from direct view of the intended target, off to the side of a probable vehicle route, usually a road, to attack the weaker armour on the sides and rear of a vehicle.

The mine can be triggered by either a contact fuze (MPB-ZK variant) or an influence fuze (MPB-ZN variant) based on infrared and acoustic sensors, and is also fitted with an anti-handling device.

When used with the passive infrared fuze, an acoustic sensor detects approaching vehicles and activates the infrared sensor, which triggers the mine at an optimal moment as the target passes.

The energy carried by the projectile is large enough that it can often significantly damage a vehicle that it hits.
