The COA defense system is not used very often thankfully, but it is still necessary. 2 long dead terrorist organizations have attacked the COA before. We also had to use our Army to defeat Danland, back when they broke away with the COA. But don't worry! The COA has many allies now, and it's not even at war with anybody. The COA has an army, navy, and many other things in it's military. All with exceptional leadership.
