The essence of war is a competitive reciprocal relationship with an adversary possessing the capacity to make choices in battle. It is impossible to anticipate and predict with precision the contours of all future conflicts and the opponent’s strategy and discrete choices on the battlefield. Recognizing the need to adapt and implement the requisite changes is therefore inherent to the nature of war. The clash of arms is, therefore, also a competition in cycles of learning, reaction, or counteraction. The side that reacts best, and perhaps faster, increases their chances of success.
