First and foremost a plan should be developed to move the casualty (IAW Unit SOP). From the point of injury, you must move the casualty to the closest position of cover, once a tourniquet has been applied, the next priority is to get the casualty to the nearest cover and out of effective enemy fire/threat. 

Carries and drags will enable responders to do this as quickly as possible without causing further harm to the casualty (if possible). Of note, at this phase of care the tactical situation prevents focusing on spinal injury prevention measures during casualty movements.
