Sorry but the Al Masdar piece doesn't make sense. Aldo posted a gelocated map, and from the look of it there's no way in hell the people attacked the lines at their longest exposure (longest distance to travel from line to line). It hasn't nothing to do with "disaster" or whatever. They're at the deepest of the no man's land. If that was during night time, yeah maybe. But it wasn't. It was in broad day light.
So they better find out what happened and who cut a deal with whom.
The movement makes no sense. They had better routes if they wanted to go forward.
But where were those men going?
That entire episode is fishy. Their chosen path/line of advance will make sense only after we get to know what that specific units objective/target was. From the video I feel the buildings (where the video is taken) from which the fire came was not their intended target and the men considered it to be a safe/secured flank ?
The footage showing the dead bodies are taken from different angle other than from where firing was shown. So its confusing, atleast for me.
In the opening and other shots of the video I do see which looks like AKs in the hands of deceased fighters, but as someone else pointed out earlier, it could have been with empty magazines...
Is it possible for you to mark the direction from where the guys came and possibly the line of advance from the videos available?
There are small walls/structures to the right side, in the direction the soldiers were running and which can be clearly seen on the right side of the soldier who is shot again when he sits up after getting injured from the earlier fire. I cant see that structure anywhere near the dead bodies in the pic you posted. In the video it appears just very close to those soldiers who probably were running to take cover behind it.
Its just out of curiosity, want to know what really happened.
