There are many different methods of attacking and defending. If you are under attack by a force of unknown size, you may wish to send troops away, and wait for the attack to end instead of keeping them, and letting them die. Attacking is quite the same. You would not normally send out defensive units for your assaults. This page is dedicatited to those who do not yet know how to survive, and is run by those who do. If you are a member of Wikia, I urge you to add what you know.
