A missile is a form of self-propelled weapon used by several species.
Missiles came in several sizes and payloads: they ranged from small-caliber, ground-to-ground missiles to humongous Cardassian ATR-4107s, with payloads made out of anything from conventional explosives to antimatter or trilithium. (VOY: "Dreadnought")
There were photonic missiles small enough so the launcher could be carried by a single marine, even though the marine could only carry one round. They were used by the Kzintis in ground combat. (RIS Bouteina: "Degree of Liberty")
