I ran across this story on another forum and thought some folks here might enjoy it. It’s the story of Staff Sergeant Reckless, a Mongolian mare who served with the the 75mm Recoilless Rifle Platoon of the 5th Marines in Korea.

Reckless also has a website (http://www.sgtreckless.com/Reckless/About_Reckless.html) which includes additional information, including the fact that after she was retired to Camp Pendleton she foaled three little marines: Fearless, Dauntless, and Chesty.
