Well, a deployed commander worth his or her salt won't go anywhere without their LEGAD and POLAD providing (generally) sound advice. And it's not all about 'Yuman rites'. It is, principally, about complying with IHL and LOAC. A few years ago I was seconded to the staff of a senior POLAD and we were linked at the waist to the LEGAD team. It was interesting - indeed astonishing - to see the target lists presented to the Joint Targetting Board by the J3/5 staff. Time and again, the POLAD and LEGAD teams would scrub through the list removing non-compliant targets - generally because they did not meet proportionality or legitimacy tests, or would have had a wider (and negative) political and
PR impact amongst the Coalition.
Yes, legal officers are still rotated through the Parish Pump of discipline and employment casework (it is surprising to see how many lawyers are still employed in BFG to maintain and interpret the SOFA - and to manage the 'behaviour' of young soldiers), but most spend a considerable time in direct support of operations. It is safe assume that there are no deliberate weapons releases made (except in self defence) that have not been scrutinised by LEGADs, inter alia.
