The order of battle of the Stormtrooper Corps is unspecified in the Star Wars universe. Accompanying the Imperial Navy, stormtroopers are able to be deployed swiftly and respond to states of civil unrest or insurrection, act as a planetary garrison, and police areas within the Galactic Empire. They are shown in collective groups of varying organizational sizes ranging from squads to legions and for some, their armor and training are modified for special operations and environments.
