Fourth Allied Tactical Air Force, 1968 (Source: Richard Tracy) A closer view of the 4ATAF / USAFE Tactical Headquarters and their radio antenna mast, with a tennis court -- and the back of a triangular German "HALT" sign -- in the foreground. The Air Force always had better equipment than the Army: even their temporary buildings seemed nicer than many of our permanent ones! The large building in the background, on the right side of the photo, is the Post Theater (Building 4673); the smaller building to the left of it is the Bowling Alley (Building 4672).
