U.S. service members salute the national colors during a transfer of authority ceremony between Task Force Thunder of the 3rd Squadron, 3rd Cavalry Regiment (outgoing) and Task Force Bulldog of the 1st Battalion, 327th Infantry Regiment, 101st Airborne Division (incoming) at Tactical Base Dwyer in Helmand Province, Afghanistan, on March 19, 2015.

As Americans were reminded earlier this week, thousands of U.S. troops are still serving in Afghanistan. Today and every day, we pray for these heroes and their families.
