One of the interesting mechanics of this game is that there is a diary from a soldier form a random division and he logs stuff you do with the division, if he dies the diaries stop
The objective was Leningrad, then he changed it to Moscow (Even though i got Leningrad sieged down and am sending siege artillery so i can barrage that shit to dust)
I forgot but it was like a mechanic in which Hitler decides on a objective, which can be one of the big 3 cities, and for you to win you just have to hold it for i think 2 months or something like that
