I'm going to go against the grain here, and say this exercise is probably exactly what they say it is.

Forget what you see in the movies. Green berets can kick doors and do all the sexy stuff if they have to (remember the Son Tay raid in Vietnam?), but their primary mission is infiltration, exfiltration, and working with indigenous forces, such as the Hmuong and the Montagnard tribesmen. These days, they're most likely working with Shiite and Christian village elders in various warm climates - which explains why they're doing this in the South over the summer.

If you ever see these guys this summer, they have failed. Their job is to train and equip indigenous forces. They don't patrol, stand guard, or fight. If they do, they have failed.

You may see some "supply" missions, to the "freedom fighters" they are working with. Again, if you do see equipment moving in and out, they have failed. These supply missions are also done secretly.

In short, I doubt that people in the states where this exercise will be conducted will see anything different. And if they do, well, then these guys need more training.

Onward and upward,
