ATLANTIC OCEAN–Quartermaster Seaman Apprentice Jacob Overturf, from Las Vegas, Nev., stands watch in the bridge of the Arleigh Burke-class guided-missile destroyer USS Mason (DDG 87), Feb. 13. Mason is underway conducting composite training unit exercise (COMPTUEX) with Carrier Strike Group (CSG) 12. The components of CSG 12 embody a “team of teams” concept, combining advanced surface, air and systems assets to create and sustain operational capability. This enables them to prepare for and conduct global operations, have effective and lasting command and control, and demonstrate dedication and commitment to becoming the strongest warfighting force for the Navy and for the nation.
