Components: The cylindrical mine body consists of a ceramic bowl containing the high explosive, with a ceramic plate which acts as the spider. These components are separated by a cushion of rubber or similar material and enclosed in asphalt-impregnated felt and tarred paper. There is a threaded opening in the top of the mine for assembly of the fuze and a bakelite plug in the bottom, which may be removed for the attachment of an anti-removal device.

Fuze: The Chemical Fuze M5 consists of a cylindrical body attached to a threaded plug. Instead of a metal safety pin, a bakelite cap is screwed on the base of the fuze body. In addition to this cap, there is a safety rin around the fuze body against the flan-ge of the plug, which prevents the fuze from being screwed into the functioning position in the mine. When the mine is armed, a pressure of 275 to 425 pounds pushes down the upper portion of the mine, overcoming the resistance of the synthetic rubber ring. The glass vial is forced down on the striker, bearing on the wooden anvil, and is broken. Mix-ture of the chemical in the glass vial with the chemical substance surrounding the vial causes a flash, which sets off the detonator, booster, and main charge.

Color: The mine is painted olive drab and marked in yellow.

Remarks: This is a non-metallic mine in order that it may not be detected by an elec-tro-magnetic mine detector.

An anti-lifting device may be attached by removing the rubber plug in the bottom of the mine; however, use of a metal device tends to defeat the purpose of designing the mine and fuze with no metal parts.

This mine is considered a substitute standard item by the Army Ordnance Department.
