Alright, commander. It's time to hit them where it hurts. Our forces have amassed right on the doorstep of Moscow. The bulk of the Red Army are still focused on the western European front, which is what gave us our opportunity to launch this campaign in the first place. Their leadership being in disarray after the death of Stalin was also a contributing factor.
While Soviet high command has been relegated to London, a victory in the heart of the motherland itself will no doubt be a blow to their morale. More importantly, the UNGDA council will feel confident we have weakened them from the eastern front sufficiently enough to finally make preparations for a full scale naval invasion of western Europe.
Your mission is to break through the enemy blockade at the city border and set up your base, then destroy all Soviet structures in the area. Be advised that there are two radar domes in the area independently calling in reinforcements, one to the north-west and one to the east. These should be your top priority. Give 'em hell, commander.
