If the casualty is responsive and able, direct them to:
Return fire.
Move to cover (if possible) and direct or expect casualty to remain engaged as a combatant if appropriate.
Apply self-aid if able or when tactically feasible, using a CoTCCC-recommended limb tourniquet for hemorrhage that is anatomically amenable to tourniquet use (within 1 minute, ideally).
If casualty is unable to move, have the casualty re-engage (if possible) in helping to establish fire superiority.
