Certainly quite interesting on paper, but I will add some comments:
88's are not so good, unless they have a restricted field of view, because they rotate very sloooooow. Over that hill they may be in real trouble when facing two or three afv at different angles.
Taking a bridge is hard against a human opponent, but not against the AI. I have seen the AI launching counterattacks across the bridge it was supposed to defend.
Keep us informed of your progress. If you make a map, consider posting a picture here.
