The first US night scope was developed by Vietnam, so I guess either the Germans lied or they did a good job destroying all traces of this scope so that neither the Americans nor the Russians copied them by the Korean War.[/quote:f638e]

To be more accurate.. The US did develop and field an infra-red "night scope" during WW2. Designated the "T3" and the later "M3" infra-red sighting devices. The M3 model was the design that would find use in Korea (again in limited numbers).
[url:f638e]http://www.ugca.org/ugca0101/ugca0101main.htm[/url:f638e] you'll find a photo of each mounted to M1 Carbines about half way down the page. The caption list the range at "about 135 yards". I think they we're most commonly used by paratrooper commando units, tho there use was very limited.

It's german counterpart.. ZG 1229 "Vampir Nachtjaeger" was a "portable" (and I use that term loosely) version of the infra-red devices that were deployed on a limited number of "Night Panther" tanks and "Uhu" observation vehicles. These also found only limited use.

Now these scopes were not the same "night vision" as is in use today, rather they consisted of an infra-red illumination beam that would light the target with infra-red light. The shooter then could see the lighted target through the coupled infra-red spectrum scope. "Starlight" night vision, the method of collecting all available light and amplifying it to a useful amount (the technology used in modern night vision) was not really in use until Nam... but there were infra-red night vision devices in limited use in WW2 and Korea.[/quote:f638e]

I wouldn't want to be stuck with one of those scopes, the lead-acid battery must have weighed a ton, like on the early "portable" radios.
