It is critical to develop a plan to move the casualty (IAW unit SOPs). From the point of injury, you must move the casualty to the closest position of cover, and afterward, you may need to move them to another position of relative safety.
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, hopefully without causing further harm to the casualty. Of note, at this phase of care, the tactical situation does not allow for spinal injury prevention measures.
