Because vanilla Generals isn't good enough for you. Realism overhauls and graphical enhancements are the main points of existence of this mod. If you want tons of new units, this is not the mod for you.
Which one should be featured in the next patch?
The left one, the centre one or the right one? Or you suck, create a new one which isn't suck like these option.
Just comment in the comment section if you literally give a fahk about it.
Note: The right one is the 0.8.3 version, in case someone actually like it.
