Help me build a more convincing shootout, please

[Blind_Justice]

I'm still happily hacking away at "Ghost In The Machine" and need a little help from people who know their way around basic military practices. See, I have never held anything more lethal than a videogame controller and my basic knowledge of tactics consists of "hit them 'til they don't move anymore", which is a bit of a problem in the scene I'm writing now. If anyone would be willing to help, you could drop me a PM and I'll send you a draft of the scene.
