Is that really what they were yelling?

Given that these soldiers are in the field occupying territory and not in a hospital, I would imagine that they are probably Russian, yes. Georgian troops have been pretty hostile to American journalists but that's just because they were led to believe America would swoop in and help them.

Tip #1 for doing a news story in territory controlled by the Russian Army: learn the Russian word for "press."

Those guys handled the situation very well. Cool, logical heads regardless of being fired upon and struck. Thanks for the link.
