The lazy way!!
If ever you are in the Single Player game and come to a building you need to destroy, but either cant be bothered to fight your way through all of the NOD inside or cant find the main control pannel - there is a much easier way!
All you need is an Ion Cannon beacon (this is somewhat overkill, but I never used the Ion Cannon Beacons besides this). Just set the beacon up inside the building (anywhere), go outside, and watch a massive beam of light decent upon the doomed building... all you need then is some popcorn.
