If you watch the unedited video, at between 2 minutes Ten seconds and Two minutes Eleven seconds, you can see that the second man from the top of the screen is carrying a loaded RPG7. The round is pointing to the top Right of the screen.

That makes this an insurgent group. The photographers have chosen to "embed" with an insurgent group, without distinctive vests that would draw attention to their status.

This is speculation, but the photo one of them took and then "shared" with the insurgents was, in my opinion going to be followed by an RPG7 attack on the Bradley AFV in the photo.

I apologise to the helicopter crew. They did exactly the right thing. The following incident with the van was unfortunate, nothing more.
