Marauder

The marauder is a terran infantry unit in StarCraft II. It replaces the firebat from earlier development builds.

Game Unit
The marauder is equipped with dual concussion-grenade launchers which reduce a biological unit's speed immediately by a set percentage. A charging zealot will still move quickly after being struck by a grenade. Slowed units are briefly covered in purple light. The marauder can slow multiple opponents in an area.

The marauder is considered an early support unit, designed to pick off early game units. It is useful for slowing down fast melee units. Marauders are better off facing mixed (light/armored) enemy forces, but are especially useful against the armored roach. They are also powerful against stalkers, immortals and, to a lesser extent, siege tanks and thors. Marauders can destroy buildings very quickly.

Development
The marauder used to have StimPacks but later lost the ability.

Trivia
The name "marauder" is most likely a reference to the novel Starship Troopers, wherein the standard powered armor suit for soldiers was called a marauder.

In pre-release versions of StarCraft I, the marine was known as the "marauder".
