Tactical Field Care, or TFC, is the care rendered by the first responder, Combat Lifesaver, and/or Combat Medic/Corpsman (CMC) and there is no longer a direct threat or under effective enemy fire. TFC also encompasses care in the combat/tactical environment not involving enemy fire, such as a parachute injury or vehicle crash.

The TFC environment allows the time and relative safety for the medic to assess and treat casualties more deliberately following the MARCH PAWS algorithm. Keep in mind that the tactical situation could revert to care under fire at any time.
