Comrade, some of the units of your First Soviet Army have escaped. I know you pity all the units that you've lost, but it's none of your fault. Nothing can stand a tactical nuclear strike. 

Your troops are now taking positions in the city of San Francisco.

The plan is to take the city population hostage, in order to negotiate surrender terms for the First Army.

These negotiations will take place without Stalin's consent. Stalin ordered to stand ground and fight to the last man, but that was obviously pure suicide.

Good luck in negotiations with the US!
