When dealing with humans, elves, and UD, you should build a beast pen to prevent the opponent from producing air units. Send bats to harass or bomb their birds, but don't just send them to bomb whenever you see their birds. You must preserve the bats and wait until the opponent attacks to bomb, and use the rest of the time to harass. Because you only have one mine, you can't compete with others for resources. If the human player produces tanks, there's no need to be afraid. In LT3C, the attack type of the human's tanks has been changed; the original siege attack has been changed to a normal attack, greatly reducing the damage to buildings. Even a full population of tanks is not a big problem. Build a beast pen in front of the arrow tower to block them. Their ground troops must destroy the beast pen first before they can reach the arrow tower, and they may not even be able to destroy the beast pen because more than ten peasants are constantly repairing it. As he attacks, I repair.
