10-23. During COA development, leaders determine whether the unit has enough combat power to defeat the force (or accomplish a task in stability or defense support of civil authorities tasks) against which it is arrayed by comparing the combat power of friendly and enemy forces. Leaders seek to determine where, when, and how friendly combat power (the elements of intelligence, movement and maneuver, fires, sustainment, protection, mission command, leadership, and information) can overwhelm the enemy. It is a particularly difficult process if the unit is fighting a dissimilar unit, for example, if an infantry unit is attacking or defending against an enemy mechanized force. Below battalion level, relative combat power comparisons are rough and generally rely on professional judgment instead of numerical analysis. When an enemy is not the object of a particular mission or tasks, leaders conduct a troop-to-task analysis to determine if they have enough combat power to accomplish the tasks. For example, a company commander assigned the task “establish civil control in town X” would need to determine if there were enough Soldiers and equipment (including vehicles and barrier materials) to establish the necessary check points and security stations within the town to control the population in town X.
