Terry Silver is definitely the army buddy Kreese calls. They did a pretty amazing red-herring by killing off the soldier that actually looked like Terry Silver though. That threw me a bit. I mean the guy looked way more like Terry Silver than Twig or whatever his name was. Then he got shot. Hmmmm. They tried to make me think it wasn't Terry Silver but it will be. It has to be. Watch Karate Kid 3 if you don't believe me.
I know it better than the others because it was so badass to me, a child.
