I am sure that they were given on my NoV! As for military stations, I never worked one though I heard them on a number of occasions, but I frequently worked the cadet stations, mainly in the regular nets to swap reports for the experiment. You may have never used the channel designators but as I remember it just about everybody else did - it was virtually universal. I also remember that as part of the experiment there were designated “fox” channels on 80 and 40, used when following the start and finish of NVIS, so there were even channels on the traditional bands.
Its pedantry, I know, but all our modern gear is channelised, tuning usually in steps of 10 Hz, only those using old analogue gear can claim to be non-channelised!
PS Even CW was channelised - there was a recommendation that CW used the USB carrier frequencies of the “fox” channels so that CW and SSB could share a channel - a bright idea that was doomed to failure because the CW made the AGC “pump”!
