TMA-3 mine

The TMA-3 is a circular Yugoslavian minimum metal anti-tank blast mine. It is very similar in appearance to the TMA-4. The mine consists of a cast circular block of explosive cased in resin reinforced fabric. The top of the mine has three fuze wells which each take a UTMA-3 fuze, and a fourth secondary fuze well is provided in the base of the mine to fit an anti-handling device. The fuze wells may also accept a number of other fuzes, including the UPROM-1, and other fuzes, potentially allowing tripwire activation. The small pressure plate area of the UTMA-3 fuzes gives the mine good resistance to minefield clearance techniques which used blast overpressure techniques i.e. explosive charges.
