A cheaper alternative is to take an APC with a nuke.. place the nuke.. get back in and and sit on it. An APC can usually take enough damage until it's too late for them to disarm it. Plus the machine gun is more effective at aiming for close range than the stealth's missles. It hasn't failed yet, assuming I can get to the building with the APC. Works great on the back side of the GDI barracks on the city map.While on the subject.. if you are in a vehicle and see a teammate place a beacon.. you might want to go assist with defending it. The situation doesn't come up very often, but it assures a successful beacon most of the time.
