Yomp
Yomp is slang originating in the British Royal Marines for a long-distance march or trek over difficult terrain while carrying full kit, often weighing up to 120 pounds including weapons, ammunition, and supplies.[1][2] The term, of uncertain etymology, entered wider usage through media reports on the grueling forced marches undertaken by British forces during the 1982 Falklands War, where Royal Marines and other units covered hundreds of miles on foot across the islands' rugged peat bogs and hills without vehicular support.[1][2] It embodies the endurance training central to Royal Marines commando preparation, emphasizing self-reliance and physical resilience under load, and has since been adopted more broadly in military contexts to denote similar laborious infantry movements.[2]
