Maribeth Ferrer, 633d Air Base Wing command chief, Col. Gregory Beaulieu, 633d ABW command, and U.S. Army Colonel Chesley Thigpen, 733d Mission Support Group commander, pose for a group photo on a 7th Transportation Battalion locomotive at Joint Base Langley-Eustis, Virginia, Dec. 1, 2021. Koscheski visited JBLE for an immersion tour to learn about the missions of units across the installation. Base visits like these allow senior leaders to interact with service members to see first-hand some of the successes and challenges faced at different installations across the Air Force. Joint Base Langley-Eustis is the only joint base in Air Combat Command. (U.S. Air Force photo by Staff Sgt. Gabriel Macdonald)
