The Rifleman's Creed (also known as My Rifle and The Creed of the United States Marine) is a part of basic United States Marine Corps doctrine. Major General William H. Rupertus wrote it during World War II, probably in late 1941 or early 1942. All enlisted Marines learn the creed at recruit training and they are expected to live by it. Different, more concise versions of the creed have developed since its early days, but those closest to the original version remain the most widely accepted.
