I served in the military for 30 years. But it was impossible to fully understand the sacrifices of our troops and their families until April 29, 2007, the day my son, First Lt. Travis Manion, was killed in Iraq. …

While my son’s life was relatively short, I spend every day marveling at his courage and wisdom. Before his second and final combat deployment, Travis said he wanted to go back to Iraq in order to spare a less-experienced Marine from going in his place. His words—”If not me, then who . . . “—continue to inspire me.

My son is one of thousands to die in combat since the terrorist attacks of September 11, 2001. Because of their sacrifices, as well as the heroism of previous generations, Memorial Day 2012 should have tremendous importance to our entire nation, with an impact stretching far beyond one day on the calendar.
