M&M:-
Anyone in any job, civilian or military, will know that little sentence on the contract of employment 'and other duties as required'.
Well, this anyone didn't know that. YLSNED, as Danny would say. Things have obviously moved on since my day. Way back when there was no contract of employment at all in the military, merely an attestation where you promised inter alia to carry out the (legal!) orders of your superiors. If that is still the case onboard HMS Bulwark then it is up to those very same superiors to ensure the maintenance of good order and discipline. I see no reason why they should not. Do you? It used to be called leadership, don't know what it's called now though.
