U.S. Marine Corps Sgt. Reckless received the United Kingdom's Dickin Medal. According to the People's Dispensary for Sick Animals, the Dickin Medal is the equivalent of the Victoria Cross and is the highest award an animal can receive while serving in military conflict.
U.S. Marine Corps Lt. Col. Michael Skaggs accepted the award on behalf of Reckless, who died in 1968.

An American author nominated the brave horse for the award after writing a book about her life.
"Her story was erased from the pages of history," author Robin Hutton told ABC News. "And when I heard about the medal, I just knew she had to get it."
Reckless was purchased from a Korean man in 1952 and went on to carry ammunition for the anti-tank division of the 5th Marines, according to ABC News.
The PSDA said Reckless learned to run for a bunker when she heard incoming artillery fire, and even ate along her fellow Marines in the mess tent.
