As A Company was clearing the final positions, Corporal McLaughlin was injured by a Czekalski recoilless rifle round fired from Wireless Ridge (reportedly the anti-tank gun operated by Corporals Julio César Canteros and Jorge Norberto González from the 7th Regiment Recce Platoon on nearby 'Rough Diamond'), and was subsequently killed by an 81mm round fired from First Sergeant Mario Ricardo Alcaide's Mortar Platoon on 'Rough Diamond' as he was making his way to the aid post.
