During the Care Under Fire phase conduct a visual blood sweep and apply CoTCCC-recommended limb tourniquet for hemorrhage that is anatomically amenable to tourniquet use. 

In Tactical Field Care, immediately apply a tourniquet, hemostatic dressing, pressure dressing, or junctional tourniquet, as appropriate, to control massive hemorrhage. Part of the assessment at this point is to perform a head-to-toe check for any unrecognized life-threatening bleeding (called a blood sweep). This blood sweep is a visual and hands-on (palpating) inspection of the front and back of the casualty from head to toe, including the neck, axillae, and groin.
