I know why I finally got The Shot. I put out all my clay's and C4's in the path I take when I take MacMillan to the chopper, so there are no enemies, then I put the clays and C4's where there are alot of troops. Then when I have to get MacMillan, I blowup my C4 and then make a run for it. And it worked!
For Mile High, I used a video on YouTube and all of my flashbangs. It takes alot of practice.
yeah ther mile high takes practice but the shot takes skill and stategy in order to win
