The pertinent question to be asked is, whether the equipment issued to members of the British Armed forces, whilst engaged in combat operations, compatibile with our NATO allies in terms of protection and efficacy. Judging by our experiences during GW2 I would suspect not.
Then Sir, I would hazard a guess that you've never worked with the Canadian/French/Spanish etc Airforces. NATO forces, by and large, are 'hanging out of their @rses' when it comes to kit, even more so than us
