Wahey! Out of bed on the wrong side today eh mj? I've yet to see an E3 that can be disguised by painting it in civvy colours and I know a lot of these terrorists are thick but they're not that thick! You're talking fluent bollocks mate.
And in answer to the original post - no I haven't seen any in civvy colour schemes but there are photos of at least one in an anniversary paint scheme - which I don't think they mind being publicised and I'm pretty sure doesn't compromise national security.
