We don't know that but we do know that unarmed soldiers are not effective soldiers. They are trained to cover, engage and return fire. With nothing to return fire with, their training doesn't do them much good.
But I'd withhold judgement until the we get all the facts. I think you'll find that the response was appropriate given the situation.
“I think you’ll find that the response was appropriate given the situation.”
I agree. I’ve already read that most if not all acted accordingly - evacing and assisting wounded to cover, blocking exits and moving targets away from the shooter. What the other poster asked for is hollywood. It was like a mortar attack for all intents and purposes - coming from someone in their own uniform and possibly coming from someone you knew well enough to think of as safe. We all wish we could act like the hollywood hero immediately, but it took only 3 minutes for the good sgt. to do so.
