According to the Army “”These deployments are a one-for-one unit replacement which leaves our overall force posture in the region unchanged. The units being replaced will return to their home station.””
I wonder who they are replacing. 101 isn’t airborne anymore. It’s a tre crearion of the Air Cavalry, now called Air Mobile. 82nd is lone Airborne Div. And 173rd in Italy is listed as a brigade but is, last I looked, a reinforced battalion.
