The computers pretty much do the same rushes of tanks and infantry. Sometimes they mix it up but are usually pretty predictable. If you're getting hit hard early focus on an initial layer of defense (against computers building defenses is fine, but most defensive buildings can be easily destroyed by another human). But be sure to keep a mobile reserve of tanks in case a ranged unit targets your defensive buildings. Once your perimeter is secure then focus on resources and you're good to win short of a bad screwup. Against the computer if you survive for 5 mins or so you're basically guaranteed a win.
