As the U.S. Armed Forces mobilize and adapt in response to a shifting threat assessment, priorities in procurement and acquisition, commercial-military integration, and application of emerging technologies have evolved as well. Amidst changes in the nature of battle, the priority of the services remains simple: sustaining the U.S. military advantage. In a candid discussion with the Vice Chiefs of the U.S. Armed Forces—General James J. Mingus, Vice Chief of Staff, U.S. Army; General Christopher J. Mahoney, Assistant Commandant, U.S. Marine Corps; Admiral James W. Kilby, Vice Chief of Naval Operations, U.S. Navy; Lieutenant General Scott L. Pleus, Acting Vice Chief of Staff, U.S. Air Force; and Vice Admiral Peter Gautier, Acting Vice Commandant, U.S. Coast Guard—moderated by Dr. Seth G. Jones, President, Defense and Security Department, CSIS, the Vice Chiefs will discuss their service-specific priorities in ensuring the military remains adaptable, lethal, and ready for the challenges ahead.
