Defense against armored cars, tanks, and other vehilces. Disable tanks and vehicles. |

COMPONENTS: |
|
The G.S. Mk IV mine 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 atta-ched to the body. During normal shipment and storage, adhesive tape binds the pres-sure plate to the mine body. |
|
(a) 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 outside casing of the mine is located the explosive main charge. |
|
(b) Fuze, Mine, Contact, A/T, No. 3 Mk I: This fuze operates on the shear pin prin-ciple, and consists merely of a spring-loaded striker retained by a shear wire. Below the striker is located 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 striker through the shear wire, and the striker spring then forces the striker into the percussion cap, firing the mine. |
|
ASSEMBLY & ARMING: |
|
Remove the adhesive tape binding the pressure plate to the mine body, and then re-move the pressure plate. Place mine in the ground and remove the paper seal over fuze well. Inspect fuze to make certain shear pin is in position, the insert the fuze and re-move the safety pin. Replace the pressure plate. CAUTION! Do not use force when attempting to remove safety pin; if it does not come away easily, discard the fuze and use another. |
|
NEUTRALIZATION: |
|
To neutralize this mine, remove the pressure plate and insert a safety pin hole in the striker. Remove fuze from fuze well. Lift the mine from the ground and replace the pres-sure plate. |
|
REMARKS: |
|
1. If mine is to be re-used, inspect the fuze to make certain that the shear pin is in position and not cut or partially cut. |
