Nice film, Nomak. Thanks for posting it! That may be the first 4v1 you've won, but it surely won't be the last.
If I could offer one suggestion that could substantially improve your situational awareness based on what I saw in the film... stop zooming in when you're shooting at someone. I notice a lot of guys do this, and while it perhaps helps them to aim, it's also an absolutely nasty situational awareness killer.
You're cutting down on your peripheral vision while zoomed in on someone, and a quick six check requires unzooming, then checking six, then reacquiring the target in the front and rezooming. That extra second could mean the difference between life and death in outnumbered situations. If you watch any of my films, you'll notice that I rarely zoom on someone unless I'm assessing a distant fight, trying to figure out a far off con's heading, or I'm shooting at a fleeing plane's straight six over 500 yards when I know no other enemies are around.
Of course, this all boils down to what you feel most comfortable doing. If you can create a more accurate picture in your head of what's going on around you than I can, then zooming in or not doesn't really matter.
