  management, legal, religious), and health service support mission sets of casually care, medical evacuation,
  and logistics. Army space operations support the sustainment warfighting function include facilitating real-
  time data transfer and visibility for an expeditionary Army. Refer to ADP 3-0 for discussions on the
  sustainment warfighting function and ADP 4-0 for information about sustainment.
  4-62. Various space capabilities are used to facilitate the implementation and decision making process for
  sustainment.
  * SSA helps clarify threat actor intent to foster protection of critical sustainment efforts.
  * PNT provides precise location of in-transit vessels enabling hyper-accurate delivery forecasts of
  resupply efforts shipped to theater. Enables precision engineer operations and infrastructure
  construction such as airfields, ports, landing zone identification, operating bases, petroleum
  pipelines, bridges, and minefields. The combat survivor/evader locator radio has en embedded
  PNT receiver device to facilitate location finding and search and rescue operations. PNT data is
  critical in providing the Sustainment COP with a clear picture of all friendly force locations and
  status. The efficient movement of Sustainment forces over large distances of the air, land, and sea
  lines of communications is most often dependent upon PNT to ensure elements arrive on schedule,
  with minimum time in transit.
  * SATCOM provides important beyond line of sight communications for real time connectivity to
  the Sustainment COP, allowing for a clear and complete picture of the location and disposition of
  Sustainment forces across large geographic areas. SATCOM provides reachback for condition-
  based maintenance, minimizing down time and reducing both maintenance and labor costs.
  SATCOM linking theaters is fundamental to timely, assured, and responsive support to the
  sustainment force. SATCOM enables reachback to technical centers and libraries, and provides
  beyond line of sight network extension. It allows tactical level G4 staffs to coordinate logistic
  requirements from deployed locations to anywhere in the world and for Sustainment planning
  staffs to receive timely battlefield updates, and update their operational plans as appropriate.
  * SATCOM and PNT are critical to beyond line of sight control and information transfer from
  unmanned aerial systems reliant on near-continuous data exchange from controllers. They enable
  engineering tools such as Tele-engineering Communications Equipment for reachback,
  Automated Route Reconnaissance Kit for route reconnaissance information, and Geospatial
  Assessment Tool for Engineering Reachback for field data collection and geographic mapping.
  Topographic engineers and geospatial planning cells require access to the space-enabled global
  information grid to update and disseminate geospatial information and products. Medical records
  can be tracked and shared through the continuum of a deployment—from point of injury to the
  sustaining base. Casualty location can be accurately identified and tracked for trends.
  * GPS, SATCOM, and imagery enable the collection and sharing of information on geography,
  supplies, services, facilities, and transportation activities.
  * Space control helps to counter adversaries from jamming communications and PNT signals.
  * Missile warning supports early warning and force protection for Sustainment units operating
  through the depth of the battlespace. Well-positioned forces helps increase timely warning so
  sustainment troops have sufficient time to take reactive measures to a threat missile event.
  * Weather and terrain data helps determine scatter patterns for chemical, biological, and
  radiological agents, and modeling of hazard predictions to support medical services or health
  services.
  * Space surveillance and reconnaissance can provide information on movement corridors, convoy
  monitoring, supply routes, and assists force protection by providing warning of enemy activity.
  They help identify weapon stockpiles, target identification, delivery systems, and dual use
  facilities. It identifies natural obstacles and provides detailed terrain information such as digital
  terrain elevation data. Combined with GPS, the information can be used for assessment of local
  utilities, land use, reservoirs, roads and bridges.
  PROTECTION
  4-63. The protection warfighting function is a continuous process executed by all commanders, regardless
  of mission, location, or threat. It consists of a broad set of unit specific, coordinated actions conducted to
