Figure and Accesories: Grand Slam v3
Grenade launcher: Marauder's Gun Runners

I thought this was a really cool looking Grand Slam, but he looks too much like my custom Flash, so I repainted his pads silver to keep with his earlier look.
His facial hair/beard looked like somebody slopped creamed spinach on his face (it was even a shade of brownish green), so I touched that up as well.
I had a hard time nailing down his exact MOS, so I made him an Indirect Fire Specialist who works with Artillary and Mortar units.
