Stalin's Blitz 2: Landing in Finland

Comrade! Your next target will be Finland - the former part of the Tsar's Russia. The weather for the operation is good - to no surprise, the operation was called a Spring War by comrade Stalin. Our intelligence reports that the Finnish army will be prepared for our strike and is forming a defensive line just before Vyborg. The line might take time to break and that's why we will be doing an amphibious landing at the back of the Finnish army. The target is simple - crush the defenders and open the way towards Helsinki!
