I wanted to have a complete noble team, and I was missing Carter and Jun. I don't have anything to make a Jun and I'll probably just buy him if I see a good deal, but I had the ac Carter from the foxtrot series blind bags. So I swapped his jumpsuit with a challenger series spartan and now have a ghost spartan or half ac spartan. I then painted Carter using an image of the Halo heros Carter for reference. Some of the paint chipped off so I'll probably fix that later, or keep it and say it's battle damage. This was the end result.
