Head: Spytroops Grunt
Arms: Steel Brigade Delta
Rest: Sgt Stone
Vest: RoC Footloose
Helmet: PoC Hawk

This Grunt figure started out with completely different parts. I think I had planned to use a Kickstart figure with Footloose vest but for some reason I changed my mind and used these parts instead. The only thing that carried over was the head and vest. The original helmet I was going to use turned out to be too big for that head so I had to find something else that had the look I wanted as well as fitting the head.
