No Base Damage from Air Strikes, Ion Cannon Blasts & Nukes
In the NOD campaign: The GDI computer player will send many A-10s with Air Strikes to your North-most base building or field unit (and in later missions many Ion Cannon blasts as well). Instead of building expensive SAM Sites to stop the Air Strikes, you can either build a Turret or other cheap building a safe distance North-West above your base and keep rebuilding it OR send a cheap Minigunner soldier far enough North of your base over and over again, so that the Air Strikes never hit your main base / army.
Do note that enemy units that are coming to attack your base will also try to kill whatever soldier is most North of all your units / buildings.
In the GDI campaign: The NOD computer player does the same thing and in later missions will keep launching Nuclear Missiles to your most-North building. Once again, you can build a Turret or another cheap building a safe distance North-West above your base and keep rebuilding it. This will save you a lot of expensive-to-repair damage during a time where Tiberium expense management is key to your victory.
Sandbagging Glitch To Box In The Enemy
In the singleplayer campaign, when you build the Sandbags (or any kind of build-able walls) they do not get recognized as an enemy target by computer players, but rather just as an environment object they ignore.
You can exploit this glitch to box the enemy in its own base, by building a wall around it, leaving them unable to attack you any further. A simpler exploit is to box in the enemy Harvester(s) with a Sandbag wall, so they run out of money and cannot attack you any more.

Regenerate Ore Every Mission
In the singleplayer campaign, whenever you find yourself running out of ore, save the game and then reload it. The ore will have fully respawned and you’ll have as much to delve for cash as you had at the start of the mission.
