138th Infantry Regiment (U.S. Army) Black Coffee Mug

The 138th Infantry Regiment is a military unit within the United States Army, falling under the umbrella of the National Guard. Established on May 26, 1917, during World War I, it has a rich history that includes participation in major conflicts like World War II and the Vietnam War. The regiment is organized into several battalions and companies across various states in the Midwest and Southeast regions of the U.S., including Missouri, Kansas, Oklahoma, and Arkansas. As part of the Army National Guard, the 138th Infantry Regiment is a reserve component, meaning its soldiers typically train part-time while maintaining civilian lives but are ready to mobilize for federal active duty when needed. The regiment's mission involves conducting sustained ground combat and stability operations in support of civil authorities during domestic emergencies or as part of multinational forces in overseas contingency operations.
