I've got a whole lot of nothing for you this morning except this clip from the movie Proof of Life starring Russell Crow and David Caruso. ***NSFW Warning: Language, gore, bad-guy-getting-his-throat-cut-out-with-a-multitool, hostiles-getting-massacred-with-a-M249***
The tactics are pretty realistic, or I should say much more realistic than most militaristic action scenes out there. I found the clip in an ARFCOM thread and thought I'd pass it along.
There are various Colt M4ish carbines, an M203, an M249 SAW, some decrepit AKs, a LAW launcher, some M67 grenades, and my favorite - what looks like a Colt officer's 1911. Enjoy.
