John Merwin, a native of Redwood City, Calif., plays with a GAU-19, an electronically-driven gatling gun aboard USS Makin Island Oct. 9. The gun is on a UH-1Y "Venom" with Marine Light Attack Helicopter Squadron 367, aka Skarface. The display was part of San Francisco Fleet Week 2010. Fleet Week showcases to the public the Marine Corps' men and women, its aircraft and equipment, and its ability to conduct missions that span the overlapping spectrums of peace and combat, from disaster relief to war.
