Given the question: Generate a question about the following movie plot: After fighting the Soviets as a volunteer during the Winter War in Finland, Max Manus returns to Norway, finding it occupied by the Nazis. He joins with the Norwegian resistance movement in their fight against the Germans but is arrested. He manages to escape to Scotland where he receives British Commando training before being sent back to Norway to carry out sabotage missions against the occupying forces. Returning to Norway with his friend Gregers Gram, his first mission is an attack on German supply ships. He is spectacularly successful, and soon he becomes a special target for the local Gestapo chief Siegfried Fehmer. Manus, however, avoids capture, and with Gram and Gunnar Snsteby he forms the so-called "Oslo Gang". Stockholm in neutral Sweden becomes a meeting point for Norwegians in allied military service. Here Gram introduces Manus to Tikken, who works as a Norwegian contact for the British consulate, and the two soon develop a special relationship. As the war becomes more and more brutal, many of Manus' friends lose their lives in the struggle against the Germans, and he starts to blame himself for being the one who survives. After the war, he meets the imprisoned Fehmer and realises that everyone is just a victim of the meaninglessness of war.[1]

What is the name of the group Max Manus forms?
