The National Security Authority has issued new measures to prevent a war conflict in the territory of your country. But some of the groups are seemingly strongly against this idea, because they have already sent their battle units to level the last base in your proximity down. You have no idea what they are doing and why, but anyway... Why are we keep destroying things? Is it really necessary? There must be an alternative way to solve this problem. Defend your territory. Defend the watchtower and destroy all units which will try to get past your defense system in order to destroy this building. Have fun.
