ADSEC, officially the Advance Section of the Communications Zone, was a military logistics unit active in the Second World War. It was the farthest forward supply unit in the US Army's European Theater of Operations (ETOUSA). The section moved forward with the armies, established by the Communications Zone, the area directly behind the Combat Zone, in order to provide close support to soldiers in combat.
