As to NVG's, I doubt we had them? This was before the NVG family came into use? PNG's as issued to ground forces were available, but like looking down 2 dustbins into a glass of lime juice.
I concur with this. I joined the Puma force (230 Sqn) in 1979 and that Squadron was still using PNG (awful) at that time. The worst thing about PNGs was that they came fitted into to a faceplate so there was no peripheral vision.We used to have to focus one eye tube on the outside world and one inside, on the instruments. This could be very disorientating. NVG (not so awful) came in a couple of years afterwards.
During my time night vision aids were not in use in Belize.
