Space marine

Two Space Marines.

Space Marines are Terrans outfitted for combat in quarters where a fighter could not access; namely, the inside of enemy ships. From what we know, Space Marines are usually only deployed for special operations.

Space Marines do not wear a space suit. They have body armor and an some sort of breathing apparatus. One eye is outfitted with some sort of targeting device. How the other eye does not implode due to the lack of pressure in space is unknown. All space marines are equipped with a machine gun that has an integrated grenade launcher. They also have magnetic boots that they can use to attach themselves to surfaces.
