Not sure if this helps any, but a friend of mine (EP3 pilot) just got dragged out of his shore tour to do this in Baghdad w/ the Army. He's been there a few weeks now. Here's an excerpt from an email: "They don't need ew experts. They picked me. From what I can see, the army never really asked for us, and my job is nothing that someone in the army can't do." Basically, the navy is touting us VQ guys as EW experts to the Army. That would be funny if it hadn't resulted in all these billets popping up out there for us.
I'm sorry to see this insanity has spread to Afghanistan, too. Anyway, not sure how much training you'll need, if any (especially if you've been through Corey Sta. or Whidbey).
