William Long, left, and Carl Mendoza, both members of the 7th Bomb Wing Honor Guard, wait to replace the 12th Air Force flag at the Air Force Global Strike Command transition ceremony Sept. 28, 2015, at Dyess Air Force Base, Texas. The transition to Global Strike Command, a command that provides secure and effective global strike operations, from Air Combat Command, which is primarily focused on direct combat and intelligence, is meant to create opportunities in training, tactics development, doctrine development, aircraft modernization, and acquisition.
