Operational conditions may require Level III units to locate offshore, in third country support bases, or in other locations. This level provides hospital care to all classes of patients. With medical resupply, it can indefinitely sustain care. It is in some environments augmented by specialty teams such as head and neck or renal hemodialysis team)

Level IV: Provided at EAC CSH. Normally augmented by more and specialized med and surgical capabilities and additional patient holding capabilities. Staffed and equipped for general and specialized medical and surgical treatment. Provides further treatment to stabilize patients requiring evacuation to CONUS.
