Yomp is Royal Marines slang describing a long-distance loaded march carrying full kit.The most famous yomp of recent times was during the 1982 Falklands War. After disembarking from ships at San Carlos on East Falkland, on 21 May 1982, Royal Marines and members of the Parachute Regiment yomped with their equipment across the islands, covering 56 miles (90 km) in three days carrying 80-pound (36 kg) loads. They were supposed to be transported by helicopters, but after the Atlantic Conveyor, which carried the helicopters, was sunk by Argentinian Exocet missiles on 25 May, the soldiers had to march across the island.
