TOBYHANNA ARMY DEPOT, Pa. Anthony Volper, an electronic digital computer mechanic here, tests the cable outputs on a Military Health System (MHS) computer network component used for data management. Members of Tobyhanna Army Depot's Computer Service and Repair Branch have configured, diagnosed and updated software for more than 28,600 MHS network infrastructure devices for Department of Defense hospitals and clinics around the world. When devices such as routers, switches, laptops or servers become non-operational, the MHS Cyberinfrastructure Services Directorate replaces them with spares maintained at the depot. Faulty devices are sent here for branch technicians to diagnose and repair. Tobyhanna's Command, Control and Computer Systems/Avionics Directorate started working on this program in the late 1990s. Cyberinfrastructure employees are responsible for evaluating, delivering and managing the network layer and all infrastructure support services for MHS. The health system weaves together health care delivery, medical education, public health, private sector partnerships and cutting edge medical research and development. The MHS consists of the Office of the Assistant Secretary of Defense for Health Affairs; the medical departments of the Army, Navy, Air Force and Joint Chiefs of Staff; the Combatant Command surgeons; and TRICARE providers including private sector healthcare providers, hospitals and pharmacies.
