In 1970, several defective lots of the directional mines were issued to soldiers in the Americal Division.
Rather than exploding as intended, the blasting cap merely knocked a chunk out of the corner of the mine.
Some soldiers unwisely gouged the explosive from the mine to use for heating their C-rations. A small
chunk of the explosive would burn quickly to heat the can of food. While some sought to blame the
malfunctions on mines that had been tampered with as a substitute for heat tablets, there was no question
that several defective lots of the Claymore mines were issued to troops in combat.
