The 38 TRS was never equipped with RB-66B models. When the 10 TRW re-equipped with the RB-66 the 38 TRS and the 32 TRS moved away from Spangdahlem (to France I believe) and re-equipped with RF-101s. The 1, 19, 30, and the 42 TRS remained at Spangdahlem until their move to the UK. The 1, 19, and 30 TRS flew the RB-66B and the 42 TRS flew the RB-66C and WB-66D. This movement of squadrons came about due to the introduction of the AFM 66-1 combined maintenance concept. It was decided to keep aircraft of one general type in the same units for maintenance and supply considerations. Fighter units got the RF-101 and bomber units got the RB-66 and these units combined accordingly.
