The anti-nuke thing only handles nukes, one of about 5 superweapons per side. (Though many of the experimentals are, quite frankly, jokes. Bad jokes.)
There is the T3 artillery unit, which can bombard your base from a long distance away -- use shields to counteract this when it first goes up, then bomb it with strategic bombers. (Better yet, just bomb it before its built by keeping your scouts going!)
The T4 units, on the other hand, are generally countered by scouting (and bombing), not letting the enemy announce their presence. If they come in range of your defensive line, your defenses are gonna get
hurt, and bad. Unless its one of the sucky T4's, like the soul reaper
