Description: The Mine G.S. Mk IV has three principal components: the loaded mine body, the pressure plate, and the fuze. The pressure plate covers the entire top of the mine and is attached to the mine body by four pins, which engage in four slots in metal clips attached to the body. During normal shipment and storage, adhesive tape binds the pressure plate to the mine body.

The mine body is cylindrical in shape and contains a central well for the insertion of the fuze. Between the central well and the the outside casing of the mine is located the explosive main charge.

The A./T. Contact Mine Fuze No. 3 Mk I operates on the shear-pin principle, and con-sists merely of a spring-loaded striker retained by a shear wire. Below the striker is loca-ted a percussion cap and detonator inserted in two C.E. booster pellets. All components – striker mechanism, cap and detonator, and booster – are contained in the fuze body.

Pressure on the pressure plate forces the striker through the shear wire, and the stri-ker spring then forces the striker into the percussion cap, firing the mine.

Use: This mine is used as a defense against armored cars, tank, and other vehicles.

Assembly and Arming: Remove the adhesive tape binding the pressure plate to the mine body, and then remove the pressure plate. Place the mine in the ground and remo-ve the paper seal from the fuze well. Inspect the fuze to make certain that the shear pin is in position, and then insert the fuze and remove the safety pin. Replace the pressure plate. Do not use force when attempting to remove the safety pin. If it does not come away easily, discard the fuze.

Neutralization: To neutralize this mine, remove the pressure plate and insert a safe-ty pin in the safety-pin hole in the striker. Remove the fuze from fuze well. Lift the mine from the ground and replace the pressure plate.

Remark: If the mine is to be re-used, inspect the fuze to make certain that the shear pin is in position and has not been cut or partially cut.
