In combat operations, sustainability as well as flexibility are paramount concern. Health maintenance and casualty management programs are crucial underpinnings of any such plans and must be thouroughly intrgrated with tactical operations. The structure and operation of medical services is essentially a function of command direction, and the decision for a specific form of supporting activity in any given maneuver is ultimately the responsibility of the operational commander.
