Space marine
Space marines are Terrans outfitted for combat in close quarters environments, such as the interior of enemy ships. They are commonly deployed in capture operations, in which case they are usually delivered to their targets via transports. The Vasudans are also known to operate their own marine corps.
Space marines do not wear a space suit. They are seen equipped with body armor and some sort of breathing apparatus. Given that parts of the body are fully exposed, they presumably do not operate in vacuum with this equipment. One eye is outfitted with what is assumed to be an ocular targeting device. They are also known to have magnetic boots for operations in zero-gravity environments. Space marines have been seen armed with automatic projectile weapons and grenade launchers.
The only direct depiction of space marines and close-quarters combat is the Hallfight cutscene, which portrayed the attempted capture of a Shivan Azrael-class transport in the Antares system.
