In 1846, the 2nd Regiment, Indiana Volunteers, Indiana Brigade was mustered into federal ervice for the Mexican–American War, and was again federalized in 1861 during the American Civil War.

### Vietnam War

Elements of the 151st Regiment served in the Vietnam War; Company D (Ranger), "Delta Company," was the only National Guard infantry unit to serve in Vietnam intact, and earned more medals in 1969 than any other Army infantry company during a 1-year period, and has been credited with reintegrating National Guard units with the United States Army after they were intentionally separated during the Vietnam War. The company was eventually assigned to II Field Force Vietnam with the mission of conducting long range patrols in War Zone D, in the III Corps Tactical Zone.
