  synchronization matrices and COA worksheets to insert IRC tasks into the war game at the time planned. A
  complete COA worksheet allows the IO officer to state the organization performing the task and its location.
  The IO officer remains flexible throughout the process and is prepared to modify input to the war game as it
  develops. The IO officer is also prepared to modify the scheme of IO, IO objectives, and IRC tasks to mitigate
  possible threat actions discovered during the war game. The IO officer notes any branches and sequels
  identified during the war game. Concepts of support for these branches or sequels are developed as time
  permits.
  4-117. The results of COA analysis are a refined scheme of IO and associated products for each COA.
  During war-gaming, the IO officer refines IRs, EEFIs, and HPTs for each COA, synchronizing them with
  that COA's concept of operations. Staff planners normally record war-gaming results, including IRC effects,
  on the G-3 (S-3) synchronization matrix. The IO officer may also record the results on the COA worksheets.
  These help the IO officer subsequently synchronize IRCs. The worksheets and synchronization matrices
  provide the basis for IO input to paragraph 3 of the OPLAN/OPORD, paragraph 3 of the IO and IRC
  appendices.
  4-118. Table 4-3 on page 4-27 provides a summary of the inputs, actions and outputs required of the IO
  officer during course of action analysis.
  COURSE OF ACTION COMPARISON
  4-119. During COA comparison, the staff compares feasible COAs to identify the one with the highest
  probability of success against the most likely adversary COA and the most dangerous adversary COA. Each
  staff section evaluates the advantages and disadvantages of each COA from the staff section's perspective,
  and presents its findings to the staff. The staff outlines each COA in terms of the evaluation criteria
  established before the war game and identifies the advantages and disadvantages of each with respect to the
  others. The IO officer records this analysis in paragraph 4 of the IO estimate.
  4-120. The IO officer determines the COA that IO can best support based on the evaluation criteria
  established during war-game preparation. The results of this comparison become paragraph 5 of the IO
  estimate.
  4-121. Table 4-4 on page 4-28 provides a summary of the inputs, actions and outputs required of the IO
  officer during course of action comparison. Table 4-3. Course of action analysis (war game)
