They are usually pretty intense and I can't help but feel some respect for people that can keep their composure in those sort of situations, but one thing I always keep on noticing is that in the descriptions of the videos and in the dialog recorded in them, the opposing force is almost always described as "Al Quaeda". Now, ignoring the fact that "Al Quaeda" is hardly known for wearing uniforms, in many of the videos the opposing force cannot even be seen by the soldiers in the video.
I certainly don't blame them for shooting back, there is nothing else you could or should do in that sort of situation, but what makes them so sure it is Al Quaeda? Couldn't it be "angry goat farmer who owns a rifle"? Are angry goat farmers with rifles de-facto Al Quaeda? Does "Al Quaeda" mean anything more than "people who shoot at us"?
Maybe they really do exist, but it seems clear to me that at the very least many of the actions attributed to it by the 'boots on the ground' are associated loosely at best.
