Unit help(modding)

I know java, lua, c#, php,css,html and a few other programing langs... BUT FOR SOME REASON the civ4 modding is strange it might be that little things like adding a leader is a few hundred line -.-(Ik you just copy and paste but still).. anyways every tutorial ive seen to make a unit it wants me to make 3d models and all these other crazy things.. all i want to do is take a unit like mechanized infantry and make like american mechanized infantry british mechanized infantry etc.. for the simple reason of maybe USA's infantry well be stronger then russias
