As Argentine landing craft were reported approaching Stanley Harbour, Marine Rick Overall fired a Carl Gustav anti-tank round which the British, in an interview with military historian Martin Middlebrook, claimed to have penetrated the side of an Argentine Marine Landing Craft Vehicle Personnel, killing all on board.
