You made a hell of a game, I agree with everybody who like the graphics, sound, performance and game play of the game. Your elaborate detailing made me feel like I was in the heat of the battles!
Please make a sequel to it maybe you can do it o WWII this time or make it on WWI again. If you are doing it on WWI here are some of my suggestions:
Units should be able to make makeshift trenches, units make defensive positions or machine gun nests, there should be medics, maybe more vehicles like armored cars or recon cars, maybe new units like a flamethrower or anti tank rifle man, maybe make new campaigns on other countries like the USA or France and maybe you should include a storyline like the genaral of an army who commands an army such and such.
Sorry for the mouthful of words :D I just thought this game really rocks sorry to say its better then your 2 last stand games XD
