'' The German weapon department came up with was called by the germans as 'die vampire' weapon system specially made for the STg44 and G43 rifle. it was an upgrade system that allows a higly tranined SS soldier to see in the Dark, and thus allows him to snipe at the advancing Allies. this was one of the few prtotypes that actually left the drawing table.
this was so effective to use in the front lines,that after the war, the American Goverment sended several scout teams to search the Country fields to find this special weapon.
In 1950 when germany was allowed to create an Army called the Bundeswehr to fight against a possible Russian attack from the East they had only a wish-list of 3 items on it.
#1. To find as much SS soldiers (believe it or not) and use them to train the new Recrouts that were avalable at the time.
#2. They searched every Ammo Dump in Germany, to recover as much Mg-42's as possible and to up-grade them into MG-45's ( Later model Mg-42.)
#3.And to recover as much as possible prototypes before the Russian found them, because you wont want to hear that you're next door Neighboor has all the good and most off all...all the Lethal Stuff!
