Two U.S. AH-64D Apache helicopters and two Kuwaiti Apache helicopters fly together during a bilateral training exercise in the Arabian Gulf, Nov. 3, 2015. The Apache crews are assigned to the U.S. Army Charlie Troop Heavy Cavalry. The joint exercise provided U.S. forces, which also included U.S. Coast Guard and U.S. Navy, an opportunity to exchange tactics and best practices with Kuwait naval forces.
