Hundreds of service members and civilians from various nations lined the road to the landing zone at NATO headquarters in Kabul. They had gathered to salute the two U.S. Marines and two U.S. Army soldiers participating in Operation Proper Exit.
Moments later, two Blackhawk helicopters swooped in, kicking up dust and debris. The four service members disembarked and walk past the cheering audience. One soldier walks with a subtle limp. One Marine has a prosthetic right arm, and the left is missing below the elbow.
