CHAPTER 8 SUMMARY OF U.S. AIR FORCE PARTICIPATION IN CASTLE Air Force participation in CASTLE was primarily in TG 7.4, with some participation in Hq JTF 7 and TG 7.1 (Scientific).

Not all Air Force personnel were badged, and since the list of such badges was the primary source of this list, it is possible that Air Force organiza- tions participated that are not listed below.
