You step out and yell incoherently in your best Russian accent. You do it so well that the soldiers assume you really are Russian and took you to their leader. You become best friends with all the FSB officers and soldiers there even though you only ever grunt in your Russian accent. They don't even mind when you slip up and reveal you're not Russian. You spend the rest of your life spying for the FSB.
The end
You win! (It's a better ending than most at least)
