Brooks & Dunn will play a private show for more than 30,000 Marines and their families at Camp Pendleton in San Diego County, Calif., on Monday (Aug. 2). The duo's stage will be constructed on the camp's beach. Rascal Flatts and Steve Holy will also perform. "These folks put their butts on the line for the values this country believes in every day," says Kix Brooks. "They don't complain or make a deal out of serving this country. They just suit and do what's asked of them, expecting nothing. To me, people who can make a sacrifice like that are people we should be thanking as loudly and powerfully as we can."
