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 missile launchers that are effective against armored targets and slow the speed of enemy units. Slowed units are briefly covered in purple light. The marauder can only slow one opponent at a time.

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. As of April 2009 they could bypass an immortal's hardened shields. Marauders can destroy buildings very quickly. The marauder is vulnerable to zealots. As a general rule, a player battling zerg should build fewer marauders than usual, while against the protoss, marauders are effective, though work well with medivac dropships as a "commando force" when battling the former.

Marauders take up double space in a bunker.

Abilities
The marauder had stimpacks as of July 2009.

Development
The marauder was originally equipped with dual concussion-grenade launchers which reduce a biological unit's speed immediately by a set percentage. A charging zealot would still move quickly after being struck by a grenade.

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

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