TMA-4

ANTI-TANK BLAST MINE

BODY:
A similar mine to TMA-3. TMA-4 is an olive drab coloured, plastic cased mine, containing a single block of cast TNT explosive. A short cord or rope carrying-handle is threaded through a small hole in the side of the mine. Three fuze wells are incorporated into the upper surface; these are threaded for UTMAH-4 fuzes.

DIMENSIONS:

 Diameter 285mm, Height 65mm + fuzes.

TOTAL WEIGHT:
 6kg.

EXPLOSIVE DETAILS:
 5.5kg cast TNT + 3 booster 10g Tetryl.

FUZE TYPE AND ACTIVATION:
Three separate, Bakelite-cased UTMAH-4 Pressure fuzes operate independently; initiation of either or all fuzes will initiate the mine. UTMAH-4 fuzes operate by chemical action: When the fuze is crushed, a friction compound inside the fuze ignites the detonator and initiates the mine.

SAFETY FEATURES:
Removal of all three fuzes will render the mine safe.

GENERAL INFORMATION:
Non-metallic mine with minimum-metal fuzes. TMA-4 is normally buried so that tops of the fuzes are at 3 to 4 centimetres below ground level. Also reported to be laid on the surface of the ground at roadblocks. Mine will activate when a pressure exceeding 100 -200kg is applied to any of the three fuzes. TMA-4 will severely damage armoured vehicles and destroy most types of non-armoured vehicles.
