  COURSE OF ACTION ANALYSIS (STEP 4)
  B-26. Course of action analysis enables commanders and staffs to identify difficulties, coordination
  problems, and the probable consequences of each course of action considered. As the staff war-games
  proposed courses of action, the G-6 (S-6) assesses DODIN operations, spectrum management operations,
  cybersecurity, and information protection feasibility. The G-6 (S-6) defines communications systems
  requirements, compares them to available assets (organic and attached), identifies potential shortfalls, and
  recommends actions to eliminate or reduce their effects.
  B-27. When determining feasibility and supportability of proposed courses of action, the G-6 (S-6) evaluates
  potential signal sites. The signal site must be defensible, and the location must not interfere with the operation
  of signal equipment. For example, structures or terrain do not block line of sight between a satellite
  communications terminal and the orbiting satellite.
  B-28. As the staff war-games proposed courses of action, the G-6 (S-6) provides signal input, including—
  * Movement of command and control nodes.
  * Emplacement of network architecture, network transport, and retransmission nodes.
  * Command and control synchronization and execution matrix.
  B-29. The G-6 (S-6) evaluates the feasibility of the communications plan for each proposed course of action,
  including the communications advantages, disadvantages, and recommended solutions for communications
  disadvantages. Upon completion of course of action analysis, operational planning continues with updating
  the commander’s critical information requirements and signal running estimate. The signal staff refines their
  scheme of signal support, ensuring that it nests with and supports the scheme of maneuver. Table B-5 on
  page B-9 identifies the key inputs, planning process, and key outputs for step 4.
