I think you just woke up and learned of the attack. There's a lot of detail that have come out and available in the thread. It's not as black and white as you just made it that hey, NATO made a mistake while conducting an opp.
The attack continued for more than two hours. On a marked and highly visible post high on top of a hill. Pak soldiers identified themselves during the course of the attack.
I suggest you go through the thread a little, and read at least few posts by professional members before coming to such a simplistic conclusion.
