Rumors on the web the last few days say that 3 of our special force troops were killed in Manbij in a missile attack.
The ISIS propaganda folks always claim more kills than they get. They have ramped up their web disinformation efforts over Manbij this last week. I have no idea if this is true (3 US SF killed), but it sounds fishy to me at first blush.
During the Fallujah offensive, ISIS and its supporters flooded reports of War Crimes and atrocities. It does suppress some fire, as the good guys try double hard to avoid mistakes. Now they are ramping up accusations in Manbij. The fog of war.
