What year did Heinrich Himmler join the unit that used the concept of Wehrbauer to refer to soldiers designated as settlers for the lands conquered during the German invasions of the Soviet Union and Poland?
Schutzstaffel The Schutzstaffel (SS; also stylized as with Armanen runes; ] ; literally "Protection Squadron") was a major paramilitary organization under Adolf Hitler and the Nazi Party (NSDAP) in Nazi Germany, and later throughout German-occupied Europe during World War II. It began with a small guard unit known as the "Saal-Schutz" (Hall-Protection) made up of NSDAP volunteers to provide security for party meetings in Munich. In 1925, Heinrich Himmler joined the unit, which had by then been reformed and given its final name. Under his direction (1929–45), it grew from a small paramilitary formation to one of the most powerful organizations in Nazi Germany. From 1929 until the regime's collapse in 1945, the SS was the foremost agency of security, surveillance, and terror within Germany and German-occupied Europe.
310th Rifle Division (Soviet Union) The 310th Rifle Division was a standard Red Army rifle division formed on July 15, 1941 in Kazakhstan before being sent to the vicinity of Leningrad, where it spent most of the war, sharing a similar combat path with its "sister", the 311th Rifle Division. The soldiers of the division fought until early 1944 to, first, hold open some sort of lifeline to the besieged city, then to break the siege and drive off the besieging German forces. They then participated in the offensive that drove Germany's Finnish allies out of the war. Finally, the division was redeployed to take the fight to the German heartland in the winter and spring of 1945. It ended the war north of Berlin with a very creditable combat record for any rifle division.
