What kind of training would make anyone think that?
Really. Who would be stupid enough to tell a grunt what the grand plan was? It was many years ago, before 9/11, that there were reports of soldiers/marines being told that they were being trained to fight against domestic threats... How is this any different?
The choice of location does make me curious... ETA:
As for the question about how was the training for that... When you have the actors screaming I'm an american citizen, what about my rights, this is unconstitutional, and stuff like that. Its pretty easy to know what they are training for.
Once again, why the fluff would you let ordinary grunts see that? If this is true, I am convinced that they *want* reports of this to get out.
