Even defence structures can't stop you. For example on map Goldrush I managed to get past defences and nuke a building. This invisibility is a big advantage, plus laser rifle is very good against infantry and vehicles. It's fun to play this class, but it is a bit overpowered atm.
What I don't get it is how people manage to place ion canon beacons in Nod base with defences? Everytime i get close to Nod base, obelisk insta kills me.
