d) Russian magnetic mine
This mine easily sticks to cars and tanks. In addition, it even sticks to painted iron and tin surfaces.
Description: the round is presumably of English make. The shape is a 14 cm long semi-cylinder. The case is full of explosives, and surrounded with surrogate. There are four magnets on the top. There are approximately 8 deep openings in each semi-cylinder for a fuse and a detonator. The fuse is held with a clamp. A standard fuse is 11 cm long, 1 cm in diameter. The delayed timer goes off in 1 hour to 3 days.
e) Tactical-technical data of T-60 and T-30 tanks.
Light tanks are not used for reconnaissance, but to guard heavy tanks. They follow medium or light tanks at a distance of 100-150 meters behind to protect them from infantry and enemy heavy tanks."
