Crab:
Yes, I'm sure they can these days but only after doing the appropriate courses and passing lots of written tests. Also they'd need to do lots of planning and a risk assessment - just in case.
Seriously though, most of the crabs we had on exchange were sorry to go back to the RAF at the end of their tours as they had grown to love using their own initiative and thinking for themselves.
Just kidding crab - even the senior service wouldn't do it without a briefing!
