Downsizer,
Sorry, my bad. Age creeping up on me. I meant the RN and their SE trade. I was one of the Air Engineering team at a Naval Air Station coping with the issues as we learnt more about NVGs, many of which had been introduced 'at the rush' for various ops. I know that the RAF and the Army had similar (but not the same) issues when NVGs arrived.
One thing we did learn was that while getting kit via Urgent Operational Requirements (UORs) can be great in the short term (and I've done many tens of them) problems can arise if the kit isn't properly brought into service later on. NVGs were a good example of that. Nobody gets promoted sorting out the 'dull and dirty' stuff downstream.
Apologies once again
Best Regards as ever to those sorting out the stuff
