“Their struggle is your struggle,” he told the ballroom crowd of former Marines and local business people. “If anyone thinks you can somehow thank them for their service, and not support the cause for which they fight – our country – these people are lying to themselves. . . .

Kelly is the most senior U.S. military officer to lose a son or daughter in Iraq or Afghanistan. He was giving voice to a growing concern among soldiers and Marines: The American public is largely unaware of the price its military pays to fight the United States’ distant conflicts. Less than 1 percent of the population serves in uniform at a time when the country is engaged in one of the longest periods of sustained combat in its history…

Months later,Kelly would struggle to describe the pain he felt on his front porch. “It was disorienting, almost debilitating,” he wrote in an e-mail. “At the same time my mind went through in detail every memory and image I had of Robert from the delivery room to the voice mail he’d left a few days before he died. . . . It was as graphic as if I was watching a video. . . . It really did seem like hours but was little more than a second or so.”
