We will see GUEST my money is on not one single person coming up with one single recorded instance of this ever happening.

And yes Jim your old soldier was shooting you a line.

I mean come on look at the supposed situation logically:

Line of armed MPs - how many? do they outnumber you? probably not

If you don't go over the top we'll shoot - What all of us?

MPs shoot one of your mates - Me along with everyone else in the Company turn round and shoot the MPs. We are after all more heavily armed than they are. It would only ever happen once and just the prospect of it would be horrific enough - Fact it never happened at all - EVER.
