Coffman,
I did some very early NVG trials and the kit was very cumbersome to use and also gave tunnel vision. One of the pilots had to be NVG free for safety. I expect that the modern kit is much improved. I recommended that the ALM did not need it 'down the back' as we always dimmed the lights to red during the 'prepare for action' stage. This allowed your vision to adjust before the exiting bit. We found the DZs at night with difficulty ! The homing radio aids available were about as 'good' as they were at Arnhem. My log book is littered with ' DZ Homing Trials'.
For strip landings at night vehicle headlights could be used and sometimes the troops held torches at the touchdown point. No doubt some of the ex SF drivers etc may be able to comment in more detail.
I have no knowledge of the current state of play.
