Marshal and Army Skills

[Matikor]

With new marshal skills I wonder if it is available to exceed squad limit. Does the system work like in previous game where marshal gains stars and just level certain skills or gains experience through certain battles ? I'd be fun to experiment with armies and gain experience for using certain armies. Like playing with archers gives you more experience with archers, faster training, more squad size and stuff. I'm really curious how the leveling system for units will turn out and what will be the caps for unit sizes. Logically with more marshal experience, ability to manage bigger armies should be a thing. With no game release atm I'm not sure how the system works already but I'd like to know how much focus is put into leveling system. Feature like that is great addition to the game and I just wonder if it's gonna just be a spin to original gameplay or whole new experience that can get you hooked in for hours. Customising army and marshals is really sandboxy thing that could add a lot of depth into KoH2 gamplay.
