Well the soviet tanks are being destroyed before they get a chance to break down [:D]
I'm using my mobile forces to penetrate in depth in soviet territory.
I avoid battle as much as possible and bypass all I can until I meet something consistant. Infantry then mope up what's left behind.
I would not go that far against a human opponent, but this game is to learn while abusing the AI

It's always fun to abuse the AI.
I'm currently playing turn 4
In the South a couple of panzer divisions drove into an undefended Kiev. While an other large enciclement has been made.
So far I'm playing on normal. The AI shows a tendency to leave citiies undefended. Maybe it should be tweaked to leave some garrisons to prevent raids in depth like I did in the South and act as spped bumps. Unopposed panzers can move quite fast. Those grand sweeps are fun though
I need to get a look at how the air force works, and also the organisational aspects. I have some reinforcements coming in and I have to see how to integrate them into the forces.
I'll kick the AI a few more turn, then I'll change sides and take the soviets. Possibly for the winter counter offensive. It could be interesting to have a look at that from the soviet side.
