  5-52. Protection consists of a broad set of unit specific, coordinated actions conducted to protect the force.
  The SSE develops and initiates protection actions during planning, but executes them mainly during
  preparation and execution. Threat assessment begins during planning and continues throughout preparation.
  Protection measures may explicitly include space operations elements.
  5-53. Resupplying, maintaining, and issuing special supplies or equipment to space operations unit’s takes
  place during preparation. Repositioning logistic assets for units assigned space operations tasks also occurs
  during preparation. The SSE coordinates with the assistant chief of staff, logistics sustainment section to
  ensure units assigned space operations tasks receive the necessary support.
  EXECUTING SPACE OPERATIONS
  5-54. Successful space operations execution relies on mutual trust and cohesive teamwork with rapid
  information exchange among them. As operations unfold, space operations objectives and tasks are modified
  to provide effective support.
  5-55. Monitoring space operations execution focuses principally on maintaining the effectiveness of space
  operations. The SSE uses the critical asset list and defended asset list to monitor the status of friendly space
  operations activities and the status of terrestrial, aerial, and space systems.
  5-56. During execution, the SSE assesses space operations execution and how to adjust space operations
  as the operation unfolds. The need for responsive staff coordination among the SSEs, headquarters, and units
  participating in space operations intensifies during execution as mission operations progress and vary from
  the OPORD. The decentralized nature of space operations execution, combined with the multiple command
  levels involved, entail a wide span of coordination for the SSE.
  5-57. Decision making during execution includes executing space operations as planned, adjusting space
  operations to a changing friendly situation, and adjusting space operations to react to unexpected enemy
  actions. Space operations may not be executed exactly as planned for a variety of reasons. The SSE’s
  challenge under adverse circumstances is to rapidly assess how changes in space operations execution affect
  the overall operation and to determine necessary follow-on actions.
  ASSESSING SPACE OPERATIONS
  5-58. Commanders and staffs continually assess operations by using measure of performance and measure
  of effectiveness. A measure of performance is an indicator used to measure a friendly action that is tied to
  measuring task accomplishment (JP 5-0). A measure of effectiveness is an indicator used to measure a current
  system state, with change indicated by comparing multiple observations over time (JP 5-0). A measure of
  effectiveness is an identifiable and measureable event or action, which tells the commander whether the
  action taken had the desired effect.
  5-59. Effects produced on and through space systems, are often not easy to assess. Rarely is damage
  physically visible or readily apparent. Assessment occurs throughout the operations process. Although
  assessment is a final step in the operations process, it also informs and guides other activities of the operations
  process. Assessment involves deliberately comparing forecasted outcomes with actual events to determine
  the overall effectiveness of force employment. Measure of performance and measure of effectiveness are key
  activities during assessment.
