Entry location: GDi missions with Mammoth tanks in them
To win most GDI missions you will need to build mammoth tanks. Once you have done that upgrade them with the railgun upgrade, (which you can get in techcenters) and you are done. Now you have a tank with formidable armor, a railgun to kill infantry and and its main cannon to decimate vehicles.
