Hellenic air force Chief Master Sgt. Siogkas Christos receives an F-15E Strike Eagle orientation tour from Staff Sgt. Trevor Wabel at Souda Air Base, Greece, during a flying training deployment, Feb. 27, 2014. Military relations between the U.S. and Greece date back to the early 19th century, when Greece was fighting for independence, as the two nations found commonality under their values of freedom and democracy. Christos works for aircrew life support and Wabel is a 494th Expeditionary Fighter Squadron crew chief. (U.S. Air Force photo/Staff Sgt. Thomas Trower)
