Definitions for "Stormtrooper"
The Stormtroopers were special military troops which were formed in the last year of World War I as the German army developed new methods of attacking enemy trenches, called "infiltration tactics". Men trained in these methods were known in German as Sturmmann (literally "storm man" or "assault man" but usually translated as Stormtrooper), formed into companies of Sturmtruppen (Storm Troops). Other armies have used the term "assault troops", "shock troops" or fire teams for specialist soldiers who perform the infiltration tasks of stormtroopers.
