Moomin,
I have to agree with Stuffy in the main, but I do take your point that the USMC would also be screwed. Let's hope it doesn't come to that.
I have to throw my lot in with the others on the security firewall (or "garden wall", which is rather a neat expression) discussion. Some that I know, that are involved, are in the usual position with that. It's not a show-stopper for them, but this programme is clearly no different to any other - as someone here said, quite rightly.
