  replacements. Accurate casualty estimates are a critical part of RSOI planning. RSOI goals are to link units
  with their equipment while maintaining a balanced flow of supplies, personnel, equipment, and units
  consistent with strategic lift capabilities and CCDR priorities.
  4-48. Sustainment commands are assigned responsibilities for RSOI operations by the ASCC. The TSC will
  normally be assigned the responsibility of RSOI. Subordinate units of the TSC from an ESC, sustainment
  brigade, CSSB, down to a movement control team can be assigned specific tasks in support of RSOI. Specific
  tasks include feeding, billeting, limited supply, finance, personnel accountability, medical, battlefield
  orientation, maintenance, and transportation of replacements to their assigned units. Support for execution of
  RSOI is provided by some combination of theater support contracts, external support contracts (primarily
  LOGCAP), regionally available commercial HNS, military assets, and Component 2 or 3 units deployed
  early. It requires sufficient capabilities and capacity to provide the support required by arriving units at PODs.
  For example, heavy vehicle operators and mechanics are required to move and repair vehicles being
  downloaded from ships for onward movement. The TSC and/or ESC directs the operation of the theater's
  PODs and the AOR distribution networks to minimize bottlenecks that may impede the flow of cargo and
  forces into and throughout the theater.
  4-49. Effective RSOI consists of the processes that transform arriving personnel and equipment into forces
  capable of meeting operational requirements in accordance with established timelines. Army units are
  attached from the supporting commander (usually FORSCOM) to the ASCC. The ASCC subsequently passes
  TACON of the unit to the sustainment command managing RSOI activities. RSOI is an ongoing series of
  four interrelated and overlapping processes that ensure synchronized clearance of nodes and assembly of
  combat power that is then rapidly transported to point of need to support operational requirements. Reception
  is the process of unloading personnel and equipment from strategic modes of transport, marshaling the
  deploying units, transporting them to staging areas, and if required, providing life support. Staging is the
  process of rapidly assembling and organizing arriving personnel and equipment into units and force packages
  that constitute combat power, and then preparing units and forces for onward movement. Life support is
  provided during reception and staging until the unit becomes self-sustaining. Onward movement is the
  process of moving combat power and supplies from reception facilities and staging areas to tactical assembly
  areas or other locations as designated by the CCDR, moving arriving non-unit personnel and replacements
  to gaining commands, and moving arriving sustainment materiel from reception facilities to distribution sites.
  The sustainment command then transfers TACON of the units to the gaining JFC or joint functional command
  for integration.
  4-50. The role of the DSB during RSOI operations is to go through RSOI and then provide support to its
  division going through RSOI. The sustainment command responsible for conducting RSOI must consider the
  DSB a tactical unit and not part of the RSOI support structure. The DSB must be able to complete the RSOI
  process and move forward to a tactical assembly area with its supported division.
  4-51. Success of RSOI is measured by force closure. Force closure is the point in time when a supported JFC
  determines that sufficient personnel and equipment resources are in the assigned operational area to carry out
  assigned tasks. It is essential during RSOI operations that data relating to arriving unit personnel, unit
  equipment, contractors, and containers be captured at each point of entry into the theater (for example,
  APODs, SPODs, railheads, and border crossings) to facilitate personnel/asset accountability and force
  closure reporting. For more information on force projection, see JP 3-35, ATP 3-35, and FM 1-0.
  4-52. The execution and support of RSOI requires a complement of various capabilities and units, which
  when synchronized and integrated, can efficiently and effectively receive and move forces (personnel and
  equipment) to key staging areas for assembly and onward movement while sustaining forces remaining
  behind. The optimal mixture of support and enablers tailored to receive forces will minimize the time it takes
  for units to maneuver through the RSOI process. Three main nodes/functions (APOD, SPOD, and ISB) are
  each slightly different in their makeup, yet connected to each other through the transportation of equipment,
  personnel, and materials. The amount of distribution assets on ground during the early phases of conflict
  directly correlate to a commander's ability to rapidly transition from crisis operations to large-scale combat
  operations. Planners should focus on the early deployment of sustainment assets during crisis. RSOI planners
  will need to assess the threat risk as well as mission priority when determining the arrival and integration of
  units and enablers executing and supporting RSOI. The most common enablers from Army sustainment
  formations required for RSOI are—
