Guards space aliens coming and you need to urgently prepare for this massive attack. Gather your troops, accumulating the bulk of the soldiers in a more likely point of impact. Carefully consider the tactics of protection, but do not get carried away with it over time, and replace the strategy of attack. Remember that every battle for you and your planet is extremely dangerous and entails certain consequences. If your army will lose, you will not be able to be on the protection of the Earth.
