Marines on 9/11: untold story

-That story is B/S.

I'll tell you a story that's not B/S.
I was still in the Army when 9/11 happened. In fact, I had been forced to retire because the military, as a whole, was dealing with a reduction of force. I was in the process of doing that when 9/11 happened.
When the airspace and borders were shut down, you may recall that the military was deployed to airports, shipping ports, and borders. Any sensitive areas went on heavy security. Military bases became hardened, tightly controlled areas.
Those machine gun nests that had a soldier behind a .50 cal machine gun, were very real.
The troops that you saw with an M16, were armed to the teeth. Their weapons were loaded.
They were green-lit to react accordingly to anyone who seemed or acted aggressively. That was a pretty broad definition with little guidance at the time.
They were also nervous, uncertain and feared for not just their lives, but for their families as well.

The fact that there were no accidental discharges of weapons, or any reports of negligence of any type, speaks volumes of the American serviceman/woman as a whole.
