Stormtrooper Motivation was the term used by the Imperial High Command for their various methods of instilling confidence into Stormtroopers. One of the more popular usually involved allowing the deaths of half the troops present followed by an official broadcast to the survivors urging them to take heart because the foe was "probably out of ammunition now." Darth Vader, being a master of such skills, could not stand amateur attempts at it. In fact, he went so far as to kill anyone who failed to motivate troopers correctly.
