A great article about En-Route Care Nursing by the Marine Corps. News. Features a few colleagues "roughing it" at Taquaddum (not that I'm complaining). We went through training at Camp Lejune, including water survival and flight training, and now cross the desert together keeping patients stable while racing them to higher levels of care.
