Custom Troop Sound Effects (Depending on the Country)

I think it would be cool if Bytro Games could add a custom language sound effect to troops.

Additionally, depending on the country, the troop (lets say, a infantry French troop) would say something in their language - such as "Allons!" (let's go!)

More examples:

вперед (Russian) ---> Onwards!Wir Gehen! (German) ---> We go! (Not sure if that is right?)

etc.
