A group of company grade officers pose for a photo during a Mission Orientation Brief of a KC-135 Stratotanker at Fairchild Air Force Base, Washington, October 6, 2017. The MOB is a week-long, stay-at-home, temporary duty tour held quarterly that contains a myriad of opportunities for CGOs anywhere on base to learn the full spectrum of Fairchild's mission.
