1st Lt. Robert M. Kelly, U.S. Marine Corps, was the son of White House chief of staff John Kelly.

But as a Marine infantry officer, 1st Lt. Kelly would want us to remember the men who fought and died alongside him. So here are the names and stories of those Marines killed in action during the 3rd Battalion, 5th Marines deployment to Helmand province, Afghanistan, 2010-2011.

Those above account for the 3rd Battalion, 5th Marines, which has suffered the highest casualty rate of any Marine unit since the Sept. 11, 2001, attacks. Yet, as we consider the lives, sacrifices, family, and friends of these men, we should also pay heed to their example. These Americans swore an oath to defend the nation and died in face of its enemies. Alongside Ernest Kernen, these Marines now stand the eternal watch in heaven.
