 The following year it was transferred to the 43d Operations Group at Malmstrom Air Force Base, Montana, when Grissom closed.This assignment was short-lived, however, because the 319th wing lost its B-1s and became an air refueling wing in December 1993 and the 905th was once more part of its operations group.Under AMC control, the unit supported Operation Deny Flight, the no-fly zone over Bosnia and Herzegovina in 1994 and 1995 from Pisa Airport, Italy and Istres Air Base, France.
