Same mod, different name, The Galactic Empire, the Rebel Alliance, the Black Sun Pirates, and the Droid Empire, fight for control of the galaxy.
They were meant to look different than normal Stormtroopers, but the stupid model isn't showing up and they keep appearing as normal Stormtroopers.
And yes they repair vehicles just like R2. I was able to give them a repair animation. These replace the repair droids that I was using. I've also added Rebel Engineers too.
Inspiration from Battlefront, perhaps?
