The Sith Troopers fall under Kylo Ren's command in Star Wars 9. 1 / 7
They're the new stormtrooper variant being introduced in the film. 2 / 7
An official Star Wars t-shirt says the battalion is under the command of Kylo and the Knights of Ren. 3 / 7
That implies Kylo and the Knights have their own army. 4 / 7
And it could be separate from General Hux and the regular First Order. 5 / 7
Kylo and Hux don't see eye to eye, so it wouldn't be surprising if they led their separate factions. 6 / 7
Maybe Lucasfilm will reveal more about the Sith Troopers during D23. 7 / 7
