It sure is something that folk have digitalized things like this. As sharp as the first printings.
The tracers are cool. We used to have a lot of various hand-gun tracers in every year's ammunition draw. The .45 and 9mm were for particular sub-caliber training devices. I think the .45 in my time was for the LAW and one of the recoil-less rifles.
The Vietnam guys specifically favored .45 tracer as an effective alternative to emergency flares as a 1911 round would almost always clear triple-canopy. We liked them later as you could call on USMC/Navy pilots with one or two where smoke or standard flares night be too 'eventful'. Oddly, the USAF was decidedly NOT accommodating to this. The trajectory of a .45 tracer was a very good thing to know though they'd usually (always?) burn out before the end.
At the end - I thought the shooting village was neat to see.
Thanks for posting.
