The ARC heavy gunner was very important to an ARC squad. His job was to destroy vehicles and turrets. He could also put up some heavy cover fire for the squad. Most people seem to think of the ARC support unit (the one with a chaingun-like weapon)as a heavy gunner. THIS is a heavy gunner, and sometime soon I'll put up a moc of my support unit. Anyways, please leave comments, and I'm always open to contests! Also, I'll update the helmet once I get around to making one.
This is a support unit.
This is the heavy gunner (I know he has the wrong helmet).
