USE:

Defense against armored cars and other vehicles. The mine will break the tracks of light and medium tanks and disable other vehicles.

COMPONENTS:

The G.S. Mk III mine has three principal components: the loaded mine body, the mine cover, and the fuze. The mine cover fits loosely over the top of the body when the mine is laid, and is raised slightly at the center to form a seating for the top of the fuze. For transit purpose the cover fits over the bottom of the mine and is secured with adhesive tape.

(a) Mine Body: The loaded mine body is cylindrical in shape and is closed at the top with a lid soldered in place. After filling, the bottom of the mine body is closed with a base plate pressed in and coated with cement for moisture-proofing. A central well in the mine body is provided for the insertion of the fuze. Immediately below the fuze well is located a C.E. booster pellet surrounding the No. 27 detonator, and below that is placed a solid T.N.T. pellet.

(b) Fuze, Mine, Contact, A/T, No. 2 Mk I: This fuze consists of a brass housing tube containing a spring loaded striker retained by a shear wire. A brass detonator holder is burred into the lower portion of the housing tube. This detonator holder contains a 1.7 grain detonator, below which is located a fire channel leading to the No. 27 detonator which is crimped over the outside of the holder. The mine is fired when the weight of a vehicle forces the cover against the striker, shearing the shear wire, and allowing the striker to be forced by its spring against the 1.7 grain detonator.

ASSEMBLY & ARMING:

Place the mine in the ground and insert the fuze in the fuze well. Withdraw the safe-ty pin from the fuze and place the cover of the mine over the fuze.

NEUTRALIZATION:

Reverse the arming procedure outlined above.

REMARKS:

1. If the mine is to be re-used, inspect the fuze to see that the shear wire is intact and in position.
