Actually, tutorial 2 is pretty good for that. You can replay it many times and see several different enemy deployments.
You can always make a random 50 CEH OoB in the editor and play it on any map you wish. You may have more units than just one corps to control, although with an OoB that size the CinC is a corps commander and the units under him are divisions.
Tutorial 3 isn't that difficult with just 3 corps to control. Give an order to one of the corps, put a second corps linked in support behind him, and send in the third corps when you see which direction the battle is going.
