Yes ARVN, French, US - also perhaps ROK, Aussie, and the odd warlord/rival revolutionary thrown in for good measure.
Not planning to be very historical, more true to the general flow of the fighting. For example during the battle for Dien Bein Phu I would try to create the sort of missions an infantry platoon/company may have been involved in inspired by actual actions rather than attempt to recreate any specific terrain or follow the action of any given unit. Where there is tension between history and game play I will design for game play every time. That said - if anyone wanted to produce historical battles which fit the campagn I'm happy to put them in.

Also, where the historical result of a major battle was very one-sided I reserve the right to go the other way - partly because even the most crushing victory at the regimental level can have a platoon which has a very bad day but mostly so reading history doesn't make the decision to opt out or press on too easy.
