This might have been answered, but I'd like to know if there is any way to change the colors of the control rods on a USA power plant?

Of course. The USA powerplants green rods are that way thanks to a skin. In order to reskin it, you must use a big extractor to open the W3D.big file in the vanilla generals directory. In there, you must extract the file "ABPWRPLANT_A1.w3d" file, including the damaged versions with the "_A1E"and "_A1D" suffixes. From there, you must make a new skin and implement it on the models in a program like RenX.

There is 3 ways... one is make it the super weapon's control rods
seond simply place USA's control rods and make a second module with Super Weapon's control rods on the same objects and have them act the same.
Third you use GMax with Coolfile's importer and renx exporter and make a new control rods W3D object... and do what DaLump said
