Another C&C exploit was that you could sell a guard tower and hit the S key during the debuild animation to cancel it.
You wouldn't get the money from selling the guard tower, but you'd get a few minigunners exit the building each time.
Then you could sell infantry units by placing them close to a sandbag, and getting the sell cursor kinda in-between the sandbag and the infantry, as close to the infantry as possible.
So you could raise a minigunner army for next to nothing, or get infinite funds from selling the troops.
