During this time RAF Croughton received most of its mission support from the 100 CG as well as some from the 100th Regional Support Group (RSG). Both of these units resided at RAF Mildenhall under the 100th Air Refueling Wing (ARW). This changed on 1 July 1994 when United States Air Forces in Europe (USAFE) conducted another command-wide reorganization. One result of this reorganization was the inactivation of the 100 RSG, its subordinate squadrons and the 100 CG. In their place, USAFE activated the 603d Regional Support Group as an independent group directly under Third Air Force. This in turn forced the redesignation of the 630 CS to the 603rd Communications Squadron.
