Medical materiel management is the supply chain work that clinical staff depends on and thinks about only when something isn't available. You'll manage pharmaceutical inventory, medical equipment, and the controlled substance documentation requirements that pharmacy and DEA oversight demand. Civilian healthcare supply chain and hospital materials management positions recruit from military medical materiel backgrounds. The pharmaceutical handling background and the clinical supply chain experience are transferable. The regulatory compliance requirements — DEA, FDA, DMLSS — give you specific knowledge that civilian healthcare employers find useful.

Aerospace physiology involves training pilots and aircrew in the physiological hazards of flight using altitude chambers and spatial disorientation simulators. When you put a pilot in a low-pressure chamber and watch them demonstrate hypoxia symptoms so they can recognize the experience in the cockpit, you're doing work that directly affects aviation safety. The career field is small and the assignments are primarily at flying training bases. The FAA aerospace medicine community and aviation training organizations recruit from this background. The specific expertise is niche and the civilian market for it is specific.
