Doesn't the "Destroy Ground" target serve this purpose already?

The destroy ground target just tells the game to give the player points for everything destroyed in a certain radius. The AI doesn't care about targets, only objects. The idea here is to give mission builders an invisible object that the AI can be assigned to attack.

To assign an object as an aircraft target is has to be in the "stationary object" list, which means it needs a class file, so that the mission builder can assign it a "red" or "blue" side. Regular static objects can't be assigned as targets.
