Maneuvering with an army is advantageous; with an undisciplined multitude, most dangerous.
Moving quickly takes a fit army that is ready to pick up and go far into hazardous territory. Rapid movement often has little time for preparation or scouting. To take on such challenges needs motivated and ready troops.
In business, sometimes you have to move quickly to take advantage of an opportunity or respond to competitive action. In such cases, there is little time for planning, training and other preparation. You must see the need and move quickly, and your people must be ready also.
This is one reason why preparation and practice is so important: there is no time on the day.
