Yomp

Yomp is Royal Marines slang describing a long distance 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 (and tabbed) with their equipment across the islands, covering eighty miles in three days carrying enormous loads.

Media coverage of this war saw the term yomp become well known and in general use. However the term has since faded somewhat from general use in the decades since the end of the Falklands war.

British Army slang for the same thing is tab. The term tab has its roots in an acronym, being an abbreviation of Tactical Advance to Battle. It has been suggested that the term "yomp" is also an abbreviation of Your Own Marching Pace.
