These are the troopers I made with my "upgrade" decals. Below is an ARC Trooper Captain, 327th Star Corps Trooper, and RC-1138.
The Trooper and Commando Decals are in my Star Wars folder. Please review!
About this creation
Star Corps Trooper
In response to "gg": Although having nice looking custom blasters for my guys would be great, I try to stick with what I know would be a decent stand-in for the weapons, like the Batman pistol for a DC-17, etc.
