While returning to camp, a small convoy of coalition soldiers traveling in a mine resistant vehicle triggered an improvised explosive device (IED). The vehicle rolled over in the blast, injuring the passengers.
Spc Walsh, a 32-year-old soldier, was treated by a field medic who reported, “The patient was in extreme pain but remained hemodynamically stable.” The medic immobilized Spc Walsh, including his leg, which was in a flexed position, locked in internal rotation. Walsh was then transported, within an hour including flight time, by a medevac helicopter to the nearest level 2 combat hospital.
