Which agency determines eligibility for physical disability retirement using line of duty determinations?

The agency responsible for determining eligibility for physical disability retirement using line of duty determinations is the Air Force. This is due to the specific role of the Air Force in managing the retirement and discharge processes for its personnel. Within the military framework, the Air Force evaluates service members' conditions to ascertain whether their disabilities were incurred in the line of duty, which directly impacts eligibility for retirement benefits.

In this context, the Air Force conducts detailed assessments to determine if the disability was a result of a service-related incident. This structured process ensures that those who have served their country are adequately supported and compensated for injuries sustained during their service.

Other agencies listed, such as the Department of Defense, the Military Health System, and the Department of Veterans' Affairs, do play significant roles in overall military healthcare and veteran services but do not specifically handle the eligibility determinations for physical disability retirement in the same way as the Air Force does for its members.
