The original Super Trooper is pretty marked with his shiny helmet, armor and shield. That was a bit of a shame, so he didn't get much playtime in my childhood. With this outfit, he doesn't look that over the top anymore, but still tough enough with that Steam-Roller torso and more realistic (usable) with those colors. I also changed the gun for one with a grenade launcher and ditched the shield.
I think this version would've been one of my favorite figures if he came out like this back then.
