Missile/Rocket launcher

A Missile Launcher fires self-propelled guided projectiles that usually contain explosive, chemical, or destructive energy warheads. Missiles may use a chemical rocket, jet engine, or something more esoteric such as an anti-gravity drive, for propulsion.
A Rocket Launcher fires unguided, self-propelled projectiles. They contain the same types of warheads as a missile. Usually rockets are propelled by an exothermic chemical reaction, but this does not preclude other forms of propulsion.
