Hi... I saw a mention of a skill tree in one of the post. I would not prefer to go into that indepth ...like diablo 3 thats way too deep I would prefer a tweak to add more sub ranks like Lance Corporal ,Sergeant Major just to expand the promotion perks system... Its really gives a sense of character developement and when that soldier gets wasted...arghhh!!! Really hope there is a genius out there who could make such a mod...cross my fingers...
