That's what the helmet cameras are for. All that's left is for the players to justify their actions. Why they shot when they did, etc...
Now, with a team of 40 engaged, how long will it take to comb the data and accurately build a picture of the sequence of events; account for each shot, who engaged who and it what order. With 40 separate feeds, I am sure you will agree it will take a heck of a long time. And besides, how many had helmet cams? And of those that didn't, how do you account for their shots and participation in the time-line? It isn't easy and it takes time. Again, the administration in this case is not lying, they are incompetent.
I am sure you have more time in combat and conducting after-action reviews than many of the combat vets here on FR. Therefore, I defer to your judgment and invite combat veterans, especially SOF, to chime in and tell us how easy it is to download helmet-cam videos and immediately come up with an accurate analysis/report.
