Nothing epitomized the outlook and performance of the German General Staff, and of the German Army which it coordinated, more than this concept of mission tactics: the responsibility of each German officer and noncommissioned officer … to do without question or doubt whatever the situation required, as he saw it. This meant that he should act without awaiting orders, if action seemed necessary. It also meant that he should act contrary to orders, if these did not seem to be consistent with the situation.
