170th Infantry Brigade (United States) - Interwar To 1970

Interwar To 1970

The brigade, along with its parent unit the 85th Infantry Division, was reestablished as part of the Organized Reserves in 1921. However, the 85th Infantry Division was reactivated on 15 May 1942, it was as a triangular division with direct control of the 337th, 338th, and 339th Infantry Regiments. Thus the brigade was disestablished.

With the reestablishment of brigades in the TOE of divisions in the 1960s following the short-lived experiment with pentomic organization, the 2nd Brigade, 24th Infantry Division was in 1963 assigned the heritage of the 170th Infantry Brigade. The 24th Division was inactivated in 1970, then reactivated from 1975 to 1996. When the 24th was reactivated again in 1999 it was as a headquarters unit only with separate National Guard brigades attached and no organic brigades of its own. It was inactivated again on 1 August 2006.
