U.S. Marines with Marine Attack Squadron 513 raise their hands during an Independence Day ceremony at Kandahar Airfield, Afghanistan, July 4. The ceremony, “Operation Red, White and True,” offered U.S. troops in Kandahar the opportunity to reenlist and reaffirm their oaths of service. “America can never thank you enough,” said Petraeus. “I think it’s important to note that unlike the soldiers of my generation, each of you joined knowing there was a possibility you’d be facing hostile combat activity.” The Marine attack squadron is deployed from Marine Corps Air Station Yuma, Ariz., to Kandahar. - U.S. Marines with Marine Attack Squadron 513 raise their hands during an Independence Day ceremony at Kandahar Airfield, Afghanistan, July 4.
