TM 65 77

The Telamiina 65 77 (Track mine model 66, with detonator model 77) is a Finnish Army standard issue anti-tank mine. The mine consists of a 9.5 kg (~21 lbs) charge of TNT. The mine is armed with a pressure detonator set to explode on a weight of 100 kg (~220 lbs). The blast effect blows off the tank's track and damages the driving wheel.

The mine is also known as the Tellu (female name, truncated form of Tellervo).
