PACIFIC OCEAN (Sept. 23, 2014) Ships from the George Washington and Carl Vinson Carrier Strike Groups and Air Force and Marine Corps operate in formation at the conclusion of Valiant Shield 2014. The U.S.-only exercise integrates Navy, Air Force, Army, and Marine Corps assets and offers real-world joint operational experience to develop capabilities that provide a full range of options to defend U.S. interests and those of its allies and partners.
