Patch WWII US ARMY ADSEC DDAY NORMANDY emroidered

ADSEC was an Advance Section, Communications Zone (COMZ), European Theater of Operations, United States Army (ETOUSA), which was formally 

activated at Bristol in February 1944. It is commonly referred to as simply "ADSEC". It was a U.S. Army logistical agency, the first 

on the continent. Upon its creation, ADSEC was attached to the U.S. First Army, and gradually took over the Communications Zone activities. 

The agency moved forward with the Armies and provided close support. ADSEC provided detail planning for the invasion of Normandy, D-Day.

As such, ADSEC did not have a "base" of operations because this support organization was designed to be on the move continuously. 

For example, major operations always had a designated "D" day or start date for operations. ADSEC units were moved into operating 

areas on or several days after a particular "D" day. They stayed until about the D+40, 

at which time FECOMZ (Forward Echelon, Communications Zone) units would take over. ADSEC units then moved forward to the next "D" location.
