20 mm x 102 TP-Marker (TP-M) is a training ammunition with a marker/spotter function. The round has an inert TP body, with a pyrotechnic-filled nose cap providing a flash effect when hitting the target, giving the same visual effect as firing live Multipurpose rounds. This provides the shooters with a realistic training scenario, without using combat rounds. It has an M50 series design and a ballistic match to the 20 mm MP M70 A2, and complies with STANAG 3585 requirements.
