Another realistic touch feature is how ammo is distributed, as your troops run out of ammo, you have to find some way of getting them back in the fight re-armed. With an engineering truck, this isn't a problem at all, however if you have gone into a minefield and your tanks tracks are blown, and he has nothing left in the barrel, things can become a bit more tense. I would not get too attached to your men either. Let's not forget that in WW2 and lots of people died, more than any other war ever fought and this is reflected in Blitzkrieg 2. Even when doing amazing high speed flanking maneuvers, a lot of your troops and tanks will suffer.
