  Figure 1-3. The operational framework in the context of the strategic framework
  1-50. The interrelationship of the air, land, maritime, space, and cyberspace domains requires a shared
  understanding of an OE. Sustainment commanders and staffs must understand the friendly and enemy
  capabilities that reside in each domain and their potential impacts to sustainment operations. Space and
  cyberspace operations that degrade sustainment information system capabilities, as well as the peer threat
  employment of conventional, special operations, guerilla, and insurgent forces to interdict friendly air, land,
  and maritime operations, can all degrade sustainment operations. Since many friendly capabilities are not
  organic to sustainment formations, commanders and staffs plan, coordinate for, and integrate joint and other
  unified action partner capabilities in an approach to operations.
  1-51. During operations against peer threats, all friendly forces must assume they are under observation and
  can potentially come into contact in all domains across both the strategic framework and operational
  framework. Understanding and visualizing the physical, information, and human dimensions within the
  context of each domain helps commanders and staffs assess and anticipate the impacts of operations. This
  includes the impact of peer threat capabilities to contest operations using space and cyberspace capabilities.
  Soldiers must be prepared to operate and communicate in denied, degraded, and disrupted environments.
  Soldiers and leaders must analyze informational considerations across the human, information, and physical
  dimensions from friendly, threat, and neutral perspectives to aid in developing ways to use, protect, and attack
  data, information, and capabilities related to sustainment operations. Sustainers at all levels should maintain
  the ability to operate in an environment where sustainment operations, data, and information are contested.
