A U.S. Marine Corps horse that served under fire during the Korean War has been decorated long after her death for bravery.

Sergeant Reckless was awarded the Dickin Medal at a ceremony at the Korean War Memorial in London last week.

The Marines bought the chestnut Mongolian mare from a Korean family after the war began. She served as an ammunitions carrier for a rifle platoon. She made more than 50 trips to supply ammunition and retrieve wounded troops under heavy bombardment during the battle of Outpost Vegas in March 1953.

After the war, Reckless retired to Camp Pendleton in California and died in 1968 at age 20.

Reckless is the 68th recipient of the medal, awarded by the PDSA veterinary charity and named in honor of the organization’s founder, Maria Dickin. It recognizes wartime bravery by animals, including a patrol collie named Rob, who made more than 20 parachute jumps during World War II.
