I cannot recall a night mountain job I have done that was called off whereby NVG would have made the decision any different
I don't know what kind of night mountain jobs you have been doing, but I have completed many where the transit to the area would not have been possible without NVG, yet alone the actual rescue itself.
NVG would undoubtedly have made many of the jobs safer
This is correct, but if this is how you view NVG then I would suggest that you have failed to fully appreciate the utility of NVG and the additional capability that they bring. As an aside, can I establish exactly what was your previous mil NVG experience?
