Tactical Combat Casualty Course students practice moving a manikin to safety during a test inside Keesler Medical Center at Keesler Air Force Base, Mississippi, Feb. 20, 2020. The TCCC is replacing self-aid and buddy care to better prepare medics for deployed environments. The course includes two classroom days where they learn about medications, how and when to treat a person when under fire and a third day where they are evaluated on everything they learned with a final scenario.
