Just by the looks of it, the sequence of events:
Civilian/Military convo op, the vehicle the camera is in is civilian, probably some sort of DipSec
The attack is triggered by two IED's on the lh/rh shoulders of the road designed to blow out the tires. If you look carefully you can tell they are fragmentation devices by the trails in the smoke of metal flying through it.
Then some sporadic Ak-47 fire, then the rhythmic sound is either a 249 or a 240G I think.
A few vehicles get in the way, and it is hard to tell if they are part of the ambush or simply civilians getting in the way.
And that is pretty much it. There are a few long strings of fire that could be the Hajis, but to me it sounded more like a LMG. Then the long strings break up into 2-3 round bursts that are most likely gunners on a humvee. Don't think the Hajis have the fire discipline for bursts like that, but I guess that is a stereotype (I don't want to lump terrorists into one general category, that would be discrimination), so I could be wrong.

I am not sure if that is what you are asking or not though. Anyway, all of that could be 100% wrong, since it is pretty hard to tell from the video.
