To some in the military, it may go without saying that war and armed conflict are complex and continually adapting phenomena. Aptly described by Clausewitz as a “duel” and “contest of wills,” it seems that every action has a reaction, that once one problem is solved a more difficult one arises, and that what worked yesterday may not work today. In contemporary conflicts, free thinking and determined adversaries continually test the limits and are continually on the lookout for patterns, seams, and opportunities to exploit. Simply put, chaos is their business.
