I was in high school '68 to '71 and attended a field day at Ft. Lost in Woods. They were demonstrating Quick Kill on the ranges - using Alka Selzter tablets, and the NCOIC worked his way down to a dime. The explanation of the program was that in Vietnam you didn't get time to work up a sight picture in the dense growth, you had one opportunity to hit the enemy in the few seconds they appeared and that's all you got.
At that time the military was already considering, testing, and USING optics, the raid to recover POWs in North Vietnam had some weapons equipped with them. http://pullig.dyndns.org/retroblackrifle/ModGde/Aces/SinglePoint.html
From there Aimpoint in Sweden developed the first commercial red dot with no erector mechanism, using a size "N" battery with a life of about 8 hours. http://www.aimpoint.com/uploads/tx_pxaaimpoint//Electronic_75_77_RF.png
I had one of those mounted on a HK91 for deer hunting in the late '70s. It IS far superior to iron sights for quick sighting and a fast shot - entirely the reason we have gone to it.
