Here are some one line ideas I've had that may already be present (I need to familiarize myself with the game/code some more):
- I saw an alienFriendly variable for nations. As regions succumb to and are assimilated by aliens, why not fight AGAINST alien-friendly humans?
- Transfer takes time, but hiring/buying is instantaneous - it shouldn't be.
- Add a selection sound list to be used when a soldier is selected on the battlescape that is nationality dependent. (e.g. a bitish-american soldier says 'yes','roger',etc.)
TODO/2.3 : Other
- [WIP] Generate soldier names depending on their nation of origin. Change team_humans.ufo so it defines names per nation rather than per class.
