Army General Frank J. Grass, Chief, National Guard Bureau and a group of distinguished visitors depart the Hobcaw Point Observation and Fishing Pier in Georgetown S.C., after observing search and rescue operations in the Great Pee Dee River as part of the 2015 Vigilant Guard South Carolina exercise. The rescue was a collaborative effort between the South Carolina Helicopter Aquatic Rescue Team and South Carolina Army National Guard Aviation using the UH-60 Black Hawk helicopter. Vigilant Guard is a series of federally funded disaster-response drills conducted by National Guard units working with federal, state and local emergency management agencies and first responders.
