“It’s time to let old things die. Snoke, Skywalker, the Sith, the Jedi, the Rebels—let it all die.” If murdering Han Solo didn’t make it obvious, Kylo Ren has become obsessed with forgetting the past. “Kill it if you have to,” he told Rey. But for someone who claims he only wants to move forward, the new Supreme Leader has picked a weird name and design for his newest stormtroopers. The Sith Troopers are reminiscent of a much older fighting squad, which might reveal just how much Ben Solo will also be looking back in The Rise of Skywalker.
Lucasfilm has revealed the new line of stormtroopers joining the First Order in The Rise of Skywalker: the stylish, red-clad Sith Troopers. Their name alone is a curious choice, since Kylo is a Knight of Ren who just said he wants to let that ancient Dark Side order die forever. That’s far from the unit’s only connection to the past, though. In addition to sharing a color scheme with Snoke’s Praetorian Guard, who Rey and Kylo literally murdered, Sith Trooper armor also looks more like the sharper-designed style worn by Clone Troop-era stormtroopers. While their gear contains elements of both the original trilogy and sequel stormtroopers, there’s a clear and obvious connection with the prequel Clone troopers, especially in the helmet.
