On this Memorial Day, American servicemembers remain deployed across the world. Many are in harm’s way. This simple fact makes the day less abstract, more real. Memorial Day is not only about wars filed away in history, but also about lives lost in service to the nation and the obligations those losses place on the living.For those who served in combat, the day is intensely personal. It is a day of names, missions, and memories that never fade away entirely. Three of the fallen return to me every year: Cpl. Andrew J. Kemple, 2nd Lt. Tracy Lynn Alger, and Sgt.The post The Lessons of Sacrifice appeared first on War on the Rocks.
