A breakthrough move and attack after combat is possible, but only if you start with a leader. There is a lot here, and when you first play this game, you will find yourself checking the rules frequently, and even movement will require a lot of chart checking. But none of this is complicated or unreasonable. It is just a long series of simple actions. There is a weather check at the beginning of each day.
Clouds can limit air power, while rain can limit all movement and combat.
The game lasts 11 days. Each day is 3 regular turns and a night turn. Long and involved, but worth it. You have to spend some time figuring out what to do and how to do it, but in the end you get a very realistic result and a close and interesting battle. More is preferred, since there are still some nasty surprises in the CRT, and you do not know how much artillery your opponent will commit to a particular defense.
