Attack helicopter

An attack helicopter is a type of helicopter that is used to attack infantry, vehicles, and buildings. They are sometimes called "helicopter gunships" because of their weapons. 
Attack helicopters can use a lot of weapons. Some of these weapons include machine guns, bombs, autocannons, missiles, and rockets. Some attack helicopters can also use air-to-air missiles for protection against other helicopters and planes.
Attack helicopters have two main purposes. The first purpose is to attack targets on the ground, like infantry, vehicles, and buildings. The second purpose is to protect transport helicopters and other weaker helicopters.
