The first phase is Care Under Fire, or in the case of a noncombat environment, Care Under Threat. In this phase, the scene is not safe, and the overall priority is to establish scene safety in the form of fire superiority or control of any threats from a noncombat environment. The TCCC Guidelines outline seven steps for the basic management plan for Care Under Fire:5

  1. Return fire and take cover. 
  2. Direct the casualty to remain engaged as a combatant if appropriate. 
  3. Direct the casualty to move to cover and apply self-aid if able or when tactically feasible, move or drag casualty to cover. 
  4. Try to keep the casualty from sustaining additional wounds.
  5. Casualties should be extracted from burning vehicles or buildings and moved to places of relative safety. Do what is necessary to stop the burning process.
  6. Stop life-threatening hemorrhage if tactically feasible.
