U.S. military aviators from several service branches make final preparations prior to one of the first live, virtual and constructive missions during Northern Edge 2015. LVC enables live participants in Alaska to directly engage and interact with virtual aviators operating from home station simulators, and constructive computer-generated forces to provide more robust training scenarios. Northern Edge 2015 is Alaska's premier joint training exercise designed to practice operations, tactics, techniques and procedures as well as enhance interoperability among thousands of Airmen, Soldiers, Sailors, Marines and Coast Guardsmen from active-duty, Reserve and National Guard units.
