I feel like the aesthetic of the First Order sort of limits how you can portray them, I think. If Sequel Trilogy had featured an Imperial Remnant that was more rebel-like, I would imagine they’re gear and equipment being pretty haphazard. I think we will see this from Remnants in the 6-7 Era, like we are with The Mandalorian, but since the stormtroopers have slick new uniforms, I feel it does limit how you can portray them to some extent. Either they are being secretly funded or they have some kind of hidden resource, like Starkiller-Starforge idea.
