FWIW I was asking because the 3rd paragraph describes the Yeomanry as being founded to prevent invasion and "formed to serve only within Great Britain" and so I was curious if it was a special-purpose unit still (and I asked about civil disturbance as clearly at some point that was a function, but perhaps later civil rights changes prevent the use of the army for policing like in the USA).

But it doesn't really matter what my intention with the comment was, clearly I touched a nerve and most folks are replying on the ethics of the issue. That probably means that it is actually an interesting topic of discussion.
