The term “capabilities” includes not only the general courses of action open to the enemy, such as attack, defense, reinforcement, or withdrawal, but also all the particular courses of action possible under each general course of action. “Enemy capabilities” are considered in the light of all known factors affecting military operations, including time, space, weather, terrain, and the strength and disposition of enemy forces.
