The critical feature of Tactical Field Care is that the casualty and responder/CLS are no longer under effective hostile fire.
However, the CLS must maintain security and situational awareness at all times while continuing to treat casualties and preparing for handoff to medical personnel/evacuation assets.
The tactical situation is often fluid and can change rapidly and revert to a CUF scenario at any time.
Your available medical equipment is still limited to that carried into the field by the casualty (JFAK), the CLS, and other first responders (JFAKs, unit combat lifesaver bag), or the medic in their aid bag. Remember to use the supplies within the casualty’s JFAK first before using your own supplies.
The TFC phase allows more time, and relatively more safety, for you to provide further medical care. You may need to continue treatment until medical personnel arrive and then assist medical personnel with continued treatment and preparation for evacuation. Anticipated time to evacuation to the next higher level of care may vary depending on the tactical situation. The CLS must be prepared to reengage the enemy and continue the mission.
Medical personnel will be focused on casualty treatment, so you and unit leaders must coordinate, and request evacuation assets based on the operational situation.
