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.
The streaming series The Mandalorian, which is set after the fall of the Empire, portrays stormtroopers as freelance mercenaries in the service of Moff Gideon, a former officer of the Imperial Security Bureau.
Background literature explains how the First Order's stormtroopers were armed in secret by the Sonn-Blas Corporation, a subsidiary of BlasTech Industries and Merr-Sonn Munitions created to circumvent the New Republic's disarmament treaties. Building on classic design templates, they are meant to possess greater battlefield accuracy, ammunition yields and operational lifespans. Examples include the F-11D blaster rifle, SE-44C blaster pistol, and FWMB-10 repeating blaster cannon. For subduing civilian populations, First Order stormtroopers will also carry ballistic riot shields and riot control batons.
The 501st Legion Elite Stormtrooper Unit, or "Vader's Fist", is a stormtrooper unit from the Star Wars movies and Star Wars Legends continuity. Commanded by the ruthlessly cunning General Maximilian Veers and composed of the best trained soldiers in the Star Wars galaxy, the legion earned a fierce reputation for completing missions considered unwinnable or suicidal. The 501st serves as Darth Vader's personal death squadron, whom he leads in the Jedi extermination. The 501st spearhead the assault upon the Tantive IV consular ship, and capture Princess Leia. During the Battle of Hoth, the 501st is instrumental in the destruction of the Rebel Alliance base, and nearly succeeds in capturing the Millennium Falcon. Most of the background story linked to the 501st comes from Star Wars novels, the games Star Wars: Battlefront II and Star Wars: The Force Unleashed, and the TV show Star Wars: The Clone Wars. 2b1af7f3a8
