From the racetrack to the battlefield—dauntless, fearless, and exemplar of Semper Fi—she was Reckless, “pride of the Marines.” A Mongolian mare who was bred to be a racehorse, Ah-Chim-Hai, or Flame-of-the-Morning, belonged to a young boy named Kim-Huk-Moon. In order to pay for a prosthetic leg for his sister, Kim made the difficult decision to sell his beloved companion. Lieutenant Eric Pedersen purchased the bodacious mare and renamed her Reckless, for the Recoilless Rifles Platoon, Anti-Tank Division, of the 5th Marines she’d be joining. The four-legged equine braved minefields and hailing shrapnel to deliver ammunition to her division on the frontlines. In one day alone, performing fifty-one trips up and down treacherous terrain, covering a distance of over thirty-five miles, and rescuing wounded comrades-in-arms, Reckless demonstrated her steadfast devotion to the Marines who had become her herd. Author Robin Hutton has reignited excitement about this nearly forgotten legend, realizing the Sgt. Reckless Memorial Monument at the National Museum of the Marine Corps, completed in July 2013, and now spurring the creation of a second memorial at Camp Pendleton, California, where Reckless lived out the rest of her days.
