I have read this thread right through and my point may have been well made already and I've missed it, or not understood some of the acronyms, if so apologies.
If crewing an aircraft that goes into or near the FEBA would it not be best for the crew, if the aircraft becomes disabled, for them to be wearing kit that is more suitable to their new conditions and also may allow them to merge with the ground troops and not be singled out for 'special' treatment if captured? I think I would prefer to look just like one of the 'lads' and without any special badges or brevets.
