Soldato
Still struggling myself. I really need to learn more about divisions and building an actual army with a goal to aim for. I'm about 30 hours in and I haven't managed to overrun a country yet. I keep trying as Germany to take over Poland, but I get destroyed once I declare war.
I've got about 220 hours into the game and think it's absolutely incredible. A mate of mine got it so we've been hammering multiplayer the last month or so. I tend to watch FeedbackGaming on youtube as he's quite funny and has really helped me understand the mechanics of the game a lot better, even though I still play on Civilian difficulty
