Which principle of Combat Treatment emphasizes providing care close to the individual's unit of assignment?

The principle of Combat Treatment that emphasizes providing care close to the individual's unit of assignment is closely associated with the concept of "Proximity." This principle reinforces the idea that delivering medical care as near as possible to the location of the injured person enhances the likelihood of prompt and effective treatment. When care is administered close to the unit, it minimizes the time between injury and treatment, which is crucial in combat scenarios where every minute can significantly impact recovery outcomes.

This principle also supports maintaining the operational integrity of military units, as it allows service members to receive necessary care without being distanced from their assigned troops for extended periods. In combat settings, the ability to swiftly provide medical intervention can mitigate complications from injuries, ultimately leading to better survival rates and faster return to duty.

In contrast, the other principles, while important in their own right, focus on different aspects of care delivery. For instance, timeliness pertains to the speed of care delivery; accessibility refers to the ability of service members to receive care; and integration involves coordinating care with other medical services or units. Proximity stands out as the specific principle that highlights the geographic closeness of treatment to the unit, making it the correct choice in this context.
