Stalin's opposition have 2 outposts in this region and a large army. We could crush them easily but Stalin doesn't want to risk too many resources as he needs them for his conquest of Europe. He wants them weakened first before committing his own forces.
Therefore he has entrusted this operation to his secret project; my life's work. I'm afraid the specifics are classified Comrade. All you need to know is this, take my agent and get him into the Command Center. Do not be fooled, he may appear as a mere spy, but he is far more than that. They will "listen" to him. Once his job is done, build your own forces and together with Stalin's, crush the remaining traitors.
Who am I? I am just a servant of the Soviet Union, like you Comrade.
Objective 1: Get the Agent into the Command Centre
