As the NVMM prepares to present our second annual Pets and Vets Week on October 19 – 22, 2022, we are reading the fascinating story of Sergeant Reckless, the mare who became a U.S. Marine and is the only animal to officially hold a military rank. Just like every other enlisted Marine, Reckless started out as a private and had to earn her promotions. Known for her enormous appetite, determined work ethic and unbreakable bond with her fellow Marines, Sergeant Reckless epitomized the Marine Corps motto of Semper Fidelis – Ever Faithful.
