Body, arms and legs: Slaughter's Marauder's Red Dog
Head: Retaliation Roadblock
Helmet: Sci- fi closed helmet modified
Weapon: ROC reactive suit Heavy duty M202 Launcher modified

While the FSS used a modified Retaliation Road Block body, I used Red Dog's buck (Bazooka torso and arms and shadow tracker legs).
Helmet used was Sci-fi's closed helmet cut open, and his main weapon is the M202 rocket launcher from RoC Heavy Duty that was slightly modified.

I also added ammo belts on his legs to emulate the original.
Hardest part was painting "The Right of Might" logo on his shirt.
