Sergeant Reckless is arguably the most heroic horse in history, having made a significant impact on the Korean War. Born in Korea and purchased from a stable boy by the US Marines, she was initially trained to carry ammunition and supplies. However, her exceptional abilities and intelligence soon made her a valuable asset in the battlefield.
On her first encounter with the M 20 recoilless rifle, Sergeant Reckless was understandably startled and jumped four feet into the air. However, with repeated exposure, she quickly acclimatized and learned to perform various tasks, including crawling under barbed wire and lying down in the face of enemy fire.

Sergeant Reckless quickly developed a strong bond with the soldiers she worked alongside. They were amazed by her courage and intelligence, and she became an indispensable part of the team. She was even allowed to roam freely around the camp and would often sleep in the soldiers’ tents on cold nights.
The mare was known for her insatiable appetite and love of scrambled eggs, chocolate, candy, and Coca-Cola. Her fondness for the latter was so great that there was a standing order for her to be given no more than two bottles a day. Sergeant Reckless’s willingness to eat anything around her, including hats, blankets, and poker chips, made her a constant source of amusement for the soldiers.
However, it was during the battle of Outpost Vegas that Sergeant Reckless demonstrated her true bravery. The Fifth Marine Regiment was facing a barrage of 180 rounds of artillery fire per minute. Despite the danger, Sergeant Reckless continued to haul ammunition up the hill, carrying 386 rounds eight at a time. She was injured twice by straps but kept charging back into battle on her own.
Sergeant Reckless’s heroic actions during the Korean War did not go unnoticed. She was given a 1700-man parade upon her return home, becoming the first and only animal ever officially promoted to staff sergeant. After retiring to Camp Pendleton, she spent the rest of her days raising her four foals and enjoying a peaceful life.
Sergeant Reckless’s story is a testament to the bravery and loyalty of animals. Despite the danger and chaos of the battlefield, she continued to perform her duties without hesitation, earning the respect and admiration of everyone around her. Her legacy lives on as a symbol of the bond between humans and animals and the sacrifices made by both in times of war.
In conclusion, Sergeant Reckless was not just a horse; she was a true hero. Her incredible bravery, intelligence, and loyalty to her fellow soldiers made her a legend in her time. Her story is a reminder of the sacrifices made by all those who have served their countries and a tribute to the power of the human-animal bond. She will forever be remembered as one of the most remarkable animals in history, a true symbol of courage and determination.
