History EditSergeant Claus Warguber was a soldier in the Afrika Korps at the time of his invention, the Kriegsmachine 1, which was a German model of the M1 Garand. Warguber had used an M1 Garand in battle in June 1942 when ammunition from his Kar98k ran out, and was amazed at the rate of fire. He tested out his own invention, and invented the WG Type 1, which was a bullet casing based off of the Springfield bullet. The weapon was rarely used, however, so he decided to make a shorter rendition of the gun, hoping for a faster rate of fire. He modified the length of the muzzle, cutting it down a few inches, and introduced the KM2 and the WG Type 2, which worked just as fine as the Type 1 in the weapon. The KM2 rifle was used in a variety of conflicts, supplied to the Blue Legion of Spanish volunteers on the Eastern Front since its invention in October.
Warguber also made designs for submachine guns, but these plans were rejected by the Reich Ministry of Supply. Warguber was relieved of his combat duties in 1944 after he was hit in the leg by shrapnel in the Battle of Mons, and he was able to focus more on his work as an engineer at home. His house was destroyed in 1945, and he was left with little money by the end of the war; his buyers were eliminated. However, he was repaid for his services and his inventions by the Allied Powers, and went on to help formulate new weapons. He formed the KM16 (all of his other models were rejected by the Wehrmacht, as stated before), which was implemented into NATO's armed wing in 1948. Warguber's company worked until he retired in 1986, and he died peacefully in 2004 in Heidelburg, his hometown.
