This version removes jet troopers from the colorable variation, due to modding limitations causing either the jet troopers or the ARC troopers to appear invisible. The fin is removed from the Phase 2 ARC Trooper helmet.

Makes the Galactic Republic's Phase 2 ARC Trooper appear as a Phase 1 ARC Trooper instead.
