As a Special Forces Intelligence Sergeant (18 Fox), it is part of the job to understand the enemy and learn everything you can about him so you can try to predict what they will do. Part of this is playing Red Team during Course of Action (COA) development, and some of it comes into play during the planning for the mission.
In preparing the Concept of the Operation (CONOP) and planning, one of the 18F’s duties is to come up with the enemies Most Likely COA (MLCOA), and Most Dangerous COA (MDCOA). It could focus on a specific target that you are going after, the Tactics Techniques and Procedures (TTP’s) that have been historically utilized, the location of these attacks, personal knowledge of the target and numerous other factors. MLCOA is usually not as dangerous as the MDCOA which, by its nature, usually takes the “worst case” option.
