154th Regiment (United States)

The 154th Regiment (Regional Training Institute) ("Third Arkansas") is a training regiment/institute of the Army National Guard. Most of its history before the 1990s can be traced to the 154th Infantry Regiment which was created from the 1st and 2nd Battalions of the 3rd Arkansas Infantry Regiment, Arkansas National Guard, in 1917. The Regiment was activated as for World War I, re-designated as the 154th Infantry and shipped to France as a part of the 39th Infantry Division, but became a replacement regiment and its personnel were reassigned to other American Expeditionary Force (AEF) units.

The 154th Infantry Regiment was never reactivated in the Arkansas National Guard following World War I. However, by 1999, it had been reformed as a Regiment (Regional Training Institute) of the Mississippi Army National Guard.
