The joke used to be:
Q: Are you in the Army?
A: No I'm a Royal Marine.
Q: Ahh so your in the Navy then??
A: No, they are merely our Taxi service.
What a crying shame that an element of truth is creeping into that comment.
Gone are the days when the RN could handle any kind of sea battle, however I would doubt that any nation would rest if they knew that a few RN hunter killers were lurking around.
