The players will start in South Vietnam, that is where the early action will occur.  I recommend US Army, or Air Force, CIA. But if you have a Vietnamese or French character in mind, run it by me.  Other nationalities are possible.  Women characters are possible, but remember that this is 1968, not the 21st century.  The past is a very different country after all.  However, simply on the basis of what they see and experience, all characters will be considered quite valuable by the US government, so allowances will be made.  Women and minority characters will thus have much greater freedom of action than they would have had historically.  But they<strong>will</strong>have occasional problems with other humans just because of who they are.  This will not apply to their dealings with the aliens.<br/><br/>Content, I'm leaving it open, will probably run the game in the Extreme forum for maximum freedom of action.  I am all about context, I don't do torture for the sake of torture, if you are worried about that.<br/><br/>This will be a system Lite game, using Mongoose Publications Traveller as a base.  If you don't have the book, don't worry, I will be handling the mechanical details.  You will be asked to make rolls, and I will be very clear about what you are rolling for and what the modifiers will be.  Your character skills and abilities will be governed more by your character concept than the formal character creation rules, but I will make sure that there are no Gods Among Us, there will be a balance between the players.  Characters can be any age from 18 onwards, I recommend no older than the early thirties.  Older characters will have more skills, younger characters will be better able to pick up skills concerning the Alien tech.  If they live that long.
