During a mass casualty response exercise, U.S. Army Spc. John Chargualaf II, an infantryman in the Guam Army National Guard and security force member for the Farah provincial reconstruction team, role plays as a wounded Soldier on Forward Operating Base Farah, Afghanistan, Jan. 23. The medical drill was planned and run by the U.S. Navy doctors, nurses and corpsmen assigned to the Forward Surgical Team located on FOB Farah. Various medical assets, including the contracted fire fighters on the FOB, the Farah provincial reconstruction team medical team, and the U.S. Army medics in the 4-73rd Cavalry, 82nd Airborne Division, participated in the exercise to test their ability to respond after an enemy attack and to triage and treat wounded personnel.
