A Royal Marine fires a mini-gun as gun crew fire a 30 mm cannon on the RFA Cardigan Bay, Royal Fleet Auxiliary, U.K. Royal Navy, during a live fire exercise with the U.S. Navy's USS Thunderbolt on June 10, 2014, somewhere in the Arabian Gulf. The Cardigan Bay worked with aircraft from the 42nd Combat Aviation Brigade (CAB) during Exercise Spartan Kopis, an exchange between the Cardigan Bay and both the Black Hawk and AH-64 Apache elements of the 42nd CAB, New York Army National Guard. Spartan Kopis was the first time American Apaches worked with a Royal Navy ship to function as its eyes and ears during an escalation of force exercise in conjunction with the Thunderbolt. (N.Y.
