Both Dunn and Peterson are assigned to the U.S. Navy guided missile cruiser USS Yorktown and are participating in the 43rd annual UNITAS exercise. UNITAS is the largest multi-national naval exercise conducted with naval forces from the U.S., the Caribbean Sea, and South and Central America. The exercises focus on building multinational coalitions while promoting hemispheric defense and mutual cooperation. U.S. Navy photo by Photographer's Mate 1st Class Martin E. Maddock.
