  in a widely dispersed, fast paced, chaotic, and highly lethal OE. Sustainment commanders must plan for and
  maintain continuity of command and control during displacement or catastrophic loss. Leaders must ensure
  units replicate frequent survivability moves and split-based operations of sustainment units and headquarters
  on a continual basis during training. In addition, measures to reduce the sustainment footprint also improve
  the mobility of sustainment forces. Movements of large numbers of vehicles cannot be adequately trained by
  simulation alone.
  DISTRIBUTION
  7-40. Large-scale combat operations will require the distribution system to move a greater volume of
  personnel, equipment, and supplies than in other types of operations. The ability to synchronize the
  distribution system to deliver the right things to the right place at the right time is critical to ensuring freedom
  of action, extending operational reach, and prolonging endurance. To be effective, commanders and staffs
  must conduct distribution management to synchronize and optimize transportation, its distribution networks,
  and materiel management with the supported unit’s concept of operation.
  7-41. Operating in extreme geography and climate conditions and around dense urban terrain presents many
  challenges to sustainment units. Units must train for OEs characterized by congested and constrained routes,
  damaged infrastructure, and 360-degree threats from above and below ground. This may include using
  autonomous aerial or ground delivery systems, provisioning special equipment and ammunition requirements
  to supported SOF, and supporting the local populace and unified action partners. Sustainment Soldiers train
  to analyze and predict the demand shifts in a dense urban environment; for example, fuel demand for ground
  forces may decrease in an AO, while ammunition requirements (particularly small-arms and terminally
  guided and precision munitions) greatly increase. Understanding distribution modes and how to request them
  is a critical part of sustainment flexibility. Distributing supplies by air or waterway may be a better option in
  a situation when motor transport is not feasible. Sustainment forces cache commodities to maintain
  flexibility. The sustainment force also trains to sustain the force in austere areas where pre-positioning
  equipment may not be feasible, adequate bases may not be available, and the industrial base and infrastructure
  are poorly developed.
  COMMUNICATIONS
  7-42. Adversaries will attempt to disrupt, degrade, manipulate, or curtail communications and access to
  sustainment enterprise systems. In response to this threat, sustainment units train to operate during degraded
  or denied communications by using redundant manual and digital control systems. To maintain command
  and control with degraded communications, sustainment units should be trained and proficient in employing
  all available command and control systems, managing information with analog processes, maintaining
  manual running estimates, and maintaining an analog COP. Developing and maintaining good staff estimates
  provides sustainment staff flexibility to anticipate requirements during degraded or denied communications.
  Sustainment operations rely on effective enterprise resource planning systems which require access to the
  DOD Information Network. Degraded connectivity to a secure communications network poses risks to
  situational understanding, command and control, mission accomplishment, and continuity of operations.
  Setup of communications to gain access is an essential task that must be trained.
  OPERATIONAL ENERGY
  7-43. Operational energy is the energy required for training, moving, and sustaining military forces and
  weapons platforms for military operations (JP 4-0). It is the energy required for operations (air, maritime,
  land, space, and cyberspace) from competition and crisis to armed conflict at all levels of warfare. Operational
  energy considerations must be included during mission planning, preparation, and constantly assessed during
  mission execution. Tracking energy production, distribution, and consumption is critical for visualization,
  risk management, synchronized decisions, and mission success. In a contested logistics environment,
  reducing energy demand is critical for prolonged endurance, flexibility, resilience, survivability, and
  extended operational range for freedom of action and sustainment. The goal is reducing energy demands by
  advancing knowledge, development, and employment of current and future capabilities thereby increasing
  the Army’s advantage. Sensoring and metering energy production, availability, and consumption is critical
  for visualization, risk management, synchronized decisions, and mission success. Energy data literacy
  integrated with data analytics creates a responsive energy management process that anticipates and simplifies
  overall sustainment requirements. Commanders and leaders at all levels should plan for, seek out, and employ
