The Nazis believed many, often contradictory, things about the Jews. One of the Nazis' favourite themes was that the Jews and the Germans were locked in some mysterious struggle for domination of Germany, Europe, even the world!

Gas chambers and crematoria.
The ovens used to burn the bodies were called crematoria.
According to the German Wikipedia, in November 1944 the SS began dismantling the crematoria in the hope of reassembling them in Mauthausen. Shortly before the arrival of the Soviet Army in Auschwitz (27 January 1945) the SS blew up the gas chambers and the remaining crematoria - and then fled.
"Crematoria" is a noun.
Treblinka was closed by the Nazis in November 1943. The whole camp, including the gas chambers and crematoria was destroyed and the area was grassed over. The Nazis tried to hide all traces of their activities.
It sounds as if you are thinking of the Sonderkommandosor 'special squads' that were forced to move corpses from the gas chambers to to the crematoria.
The gas chambers were given various euphemisms. Since the war they have generally been referred to by the by the building in which they were contained; the crematoria.
When the Nazis retreated from Battle of Britain, they launched Operation Barbarossa, which was the invasion into the Soviet union.
The crematoria did not kill people; people were killed in the gas chambers, then the corpses were cremated in the crematoria.
Operation Overlord.

The only weapon really used in the Holocaust were Gas chambers using Zyklon-B rodenticide gas, (killing so many the extermination-camp crematoria had to run continually). Before this, many victims were simply shot, but the Nazis realised this was too inefficient for their mass-murder policy, and had bad psychological effects on the soldiers involved.
