Look, this has been rumor for a very long time. It's bullshit. If your Drill Sgt friend is telling you this, he is full of shit. Prove it. I'd actually like you to. You can't, because that shit would be on the news. Don't believe everything you hear. If you actually believe this, I need you to get me an exhaust sample from the Strykers, or a box of grid squares...
