I just looked at the Harris rules, and it does say that the land units cannot retreat into a country that only a plane came from. However, it also says that the planes can retreat, and all land units stay. To this point, my group has used the avalon hill game rules to the word, just so we don’t have people constantly wanting to change the rules. The rules affect everyone equally, so who really cares what they are. However, if the larry harris rules are more specific about the ambigueities of the game rules, then maybe we’ll have to switch.
