Tech Tree Focus USSR Nov. 19th-23rd

GeneralDirection: I will take the blame for this since I approved the event. It should have been tier 3-7, but somehow was changed to tier 2-6. I'll try to get the tier 7 TD (at least one of them) added in early December, but I can't promise it'll happen since development has already started on December events and they're moving through the QA process now.
