Tech. Sgt. Joshua Crook, 51st Medical Operations Squadron noncommissioned officer in charge of ambulance services, carries a simulated casualty during a two-day Tactical Combat Casualty Care training course on Sept. 25, 2019, at Osan Air Base, Republic of Korea. Team Osan medics spent the first day of training in a classroom setting learning advanced skills in bleeding, airway and intravenous therapy (IV). Day two gave the medics an opportunity to apply these techniques during training lanes in simulated care-under-fire scenarios. (U.S. Air Force photo by Tech. Sgt. Matt Davis)
