Possibility of these games?

The problem is, that you cannot prohibit the allied player (ARVN+friends) from moving into areas that were historically "no-go" (Laos, N. Vietnam etc.), apart from house rules. In addition, there is little way to model the political constraints on use of weapons (cease fires, bombing stops etc.). A possible way to represent he communist forces disengaging at will, would be to make all of their units "Deception" units, thus allowing them to go into deception mode on top of another friendly unit, only to reappear next turn as they are recalled.
