A Marauder is a type of Peacekeeper craft.
Marauders are the primary recon/commando dropship in the Peacekeeper fleet. They have excellent scanner equipment and good stealth capabilities, and are typically used as scouts and troop transports for boarding missions. Each Marauder is heavily shielded and carries up to 5 highly trained and well armed Peacekeeper commandos.
When a ship lands, people leave through an elevator system located in the rear landing stalk.
In a combat situation a marauder can deploy its commandos through a bottom hatch without having to land. Marauders have a reported top speed of hetch 7.
Cesium fuel: Cesium is one of the alkali metals. It reacts explosively with water, is liquid at or near room temperature, and has more isotopes than any other element. Humans use it for photoelectric cells and the Peacekeepers use it for fuel.
Marauders are equipped with pulse cannons, located in the two front landing stalks, and missiles. Marauders are sometimes assigned as part of a Peacekeeper Retrieval Squad, often used to capture and enslave Leviathans.
