Need help with altering a texture

Hey gus, I have been working a modified model of the M1A2 Abrams TUSK of CoD: Ghosts. I wanted to recreate an M1A1 Abrams like those used in Kuwait 1991. So, I have removed the Tank Urban Survival Kit (TUSK), added some bags and stuff to the model, made the drivers cabin in the front, the wheels (whatever you want to call them) are more detailed (with bolts and stuff).

Anyway, here comes my main problem and I really hope someone can help me. The textures look really worn and rusty:

I want it to look like the flat desert tan used in 1991 (basically like this:)

I don’t really have those 2D graphic capabilities of making it nice looking. Either the details on the texture will fade away or it looks just awkward. If someone could help me, that would be really appreciated.
