History Main / SpaceMarine

* ''VideoGame/{{Onslaught}}'' sees you as the captain of a space marine platoon fighting a BugWar on an uninhabited planet.

* Kainan, the protagonist of ''Film/{{Outlander}}'', was a space marine in the BackStory. In the movie itself, he quickly loses his space-armor and gun, and essentially gets adopted as a [[HornyVikings Viking]].

* "TabletopGame/{{Lancer}}'' has "Space Marine" as one of many hats the titular mech pilots can wear. Special mention goes to Union's [=DOJ/HR=] Liberation Teams, the most hardcore Union strike teams sent to liberate entire planets from tyrannical masters who refuse to respect the Utopian Pillars; as well as Albatross, an anti-pirate knightly order funded by [=IPS-N=] to protect their shipping lanes from pirate attacks. [=IPS-N=] suits are often created for shipboard action, with the Caliban in particular being closer to a suit of PoweredArmor then a MiniMecha, designed to clear pirate ships singlehandedly.

* The setting of the ''TabletopGame/Warhammer40000'' tabletop game and assorted derived media, which include computer games, comic books and bestselling novels, prominently features an army of warriors known more properly as the Adeptus Astartes, but most often referred to as simply the Space Marines. Not only is he a holistic WarriorMonk in bulky PoweredArmour, who wields a lot of [[MoreDakka big guns]], kills aliens, heretics, and mutants with ease, and [[NervesOfSteel knows no fear]], he's ''also'' a genetically engineered SuperSoldier with a [[ChurchMilitant fanatical devotion to the Emperor]]. In summary, the trope {{exaggerated|Trope}}. They're generally considered the SpotlightStealingSquad of the setting, and have a number of sourcebooks dedicated to them. These guys can suffer from SeinfeldIsUnfunny, being such a long-running franchise.

* Space Trooper is one of the 10 original ring sets available in "[[Website/GaiaOnline zOMG!]]". Its primary focus is on ranged attacks, and its skills include firing CoolGuns, altering its density, and summoning a BeehiveBarrier.

* Season 2 of ''Series/ForAllMankind'' features US Marines on the Moon, sent to secure mining claims disputed by the Soviet Union.

* Heinlein's earlier ''Literature/SpaceCadet'' actually features Space Marines under that name. The protagonist, a member of the Space Patrol, considers transferring but is convinced to do otherwise by his mentor. As he explains, the branches of the Space Patrol tend to attract different men: the Marines attract those who seek glory and excitement, the Patrol attracting men of intellectualism and idealism, reflected in [[PretentiousLatinMotto the Patrol's motto]] -- ''[[WhoWatchesTheWatchmen Quis custodiet ipsos custodes?]]''[[note]]Who will guard the guardians?[[/note]] The protagonist elects to remain in the Patrol.

* The US Marine Corps becomes this in Creator/IanDouglas's ''Literature/GalacticMarines'' series. In fact, the very first novel ''Semper Mars'' starts off with the corps about to be disbanded, as the higher-ups claim it's no longer relevant. As a last-ditch effort to rebrand the marines, a detachment is sent to the Martian excavation site in Cydonia. This proves to be the exact place where they will be needed when [[spoiler:the [[UnitedNationsIsASuperpower UN]] starts a war with the US]]. Several issues are mentioned, such as the fact that their gear isn't up to specs because someone back on Earth assumed they were going to an Earth-side desert environment (e.g. their guns' electronic sights are calibrated for Earth gravity and atmosphere, and they have 40 pairs of desert boots which they can't wear with their sealed suits). The same book also features the first ever combat in microgravity with a different team of US Marines fighting a force of [[spoiler:UN troops]]. The differences are showcased, such as the lack of cover in space, the need to fire your weapon at your center mass in order to avoid to spin wildly out of control, and the fact that even a tiny hit can be fatal due to the vacuum outside the suit.
* The space marines the ''Literature/{{Nameless War}}'' are there to provide Battle Fleet with an organic infantry force for rapid deployment, the expectation being that in the event of larger operations, elements of the national militaries will be deployed. While not equipped with a fully enclosed power armour, the marines do wear a supporting exoskeleton that allows them to carry armour far heavier and more protective than could otherwise be carried. The marines are primarily intended for operations on planets [[spoiler: but do storm an enemy space station.]]

* ''Webcomic/SchlockMercenaries'': Spaceship-to-spaceship combat using boarding parties is still a thing in the 31st century, and the protagonists (including Schlock) have been on both the giving and receiving end of it several times. Due to the prevalence of advanced AI and even more advanced gravitics, however, boarding actions are exclusively done to civilian vessels, or to capture surviving crew after a warship has been disabled (either by killing the AI or the ship's power plants). Trying to teraport troops into a fully functioning warship will end up with the boarders being [[GravityMaster gravy gunned]] [[ChunkySalsaRule into gravy]] long before they become a threat.

* While space-based boarding actions exist in the lore, generally these tend to involve pirates, mutineers or hostage takers (and those seeking to battle them). Boarding a civilian vessel like a merchant craft or [=JumpShip=] involves using [[HumongousMecha BattleMechs]] with magnetic soles to attach to the outer hull and disabling the engines, and then using shuttles of infantry equipped with shotguns, light laser weapons and hull-cutters to sweep the ship and seal the deal. Boarding actions are not considered part of actual space combat doctrine by either the Inner Sphere or the Clans: Anything that carries external weaponry, like a military [=DropShip=], is generally capable of swatting down boarding parties well before they can touch base, and [=WarShip=] combat involves kilometre-long ships shooting at each other from distances where boarding is no longer a viable strategy.

* Elite Clan infantry in the ''TabletopGame/BattleTech'' universe are, indeed, located somewhere inside armor the size of four brick shithouses. The subversion is that these Space Marine stand-ins are chosen to be infantry in a galaxy where HumongousMecha are kings of the battlefield, so they're already seven feet tall plus and ripped to shit, and then they're put inside armor that allows them to survive in extreme heat, cold, the vacuum of space, underwater, and fly through the air... hence their name: Elementals.
** Then there's their reputation of being able to rip open [[HumongousMecha Battlemechs]] like tin cans, given a [[ZergRush sufficient numerical advantage]].
** With emphasis on ''Elite''. Elementals are ''[=BattleTech=]'' universe's equivalent of [[TabletopGame/Warhammer40000 Astartes]]: Genetically engineered giants equipped with powerful battle armor designed to tear the shreds out of all opposition, especially much larger Battlemechs. The Clans also have regular infantry but they're treated as little more than CannonFodder.
** This is about the point where we should mention that the Inner Sphere on the other hand also has huge suits of powered armor in a wide variety of shapes and sizes (which the Clans are catching up to), but have to make due to regular men and women inside of them. They also make use of regular infantry, which can be on foot, riding in/on vehicles, or using jet packs.
** A particular Inner Sphere example belongs to the mercenary outfit known as the Grey Death Legion. The Legion was the first to use power armor extensively, not only for infantry combat, but for getting close ''and blowing the legs off battlemechs.'' The GDL's anti-mech units are as close to BadassNormal as the [=BattleTech=] Universe will allow.

* The basic human unit in ''Franchise/StarCraft'' is the Marine. The "lots of big guns" aspect sets it apart from the basic units of the other races, giving it range. Despite all the bulky armour and training and the fact that most of them are ''Badass'' convicts that have been brainwashed to risk the life for the force they serve, they happen to be one of the weakest units in the game individually. Goes to show how powerful everything else in the game is. Badass inflation strikes again. It is, however, a testimony to the versatility of the Terran Marines that 'M&M' (Marine and Medic in ''[[VideoGame/StarCraft1 SC1]]'', Marine and Medivac in ''[[VideoGame/StarCraft2 SC2]]'') is considered a solid build for most situations and has consistently been a headache to balance against. They're the only cannon fodder in both games with ''anti-air capability'' (the Zerg Queen and Protoss Sentry being closer to vehicles and much less expendable).

* ''Franchise/DeadSpace'': {{Subversion}}: The main character, Isaac Clarke, has the armor, weapons, and coolness of a Space Marine... And he's a ''[[TheEngineer repairman]]'': his "weapons" are [[ImprovisedWeapon tools for mining and repairs.]]

* The basic human unit in ''VideoGame/StarCraft'', by far the most-played RealTimeStrategy game ever, is the Marine.

* Homaged in ''Fanfic/RocketshipVoyager'', where the eponymous rocketship has space marines in place of {{Red Shirt}}s. The two mentioned by name are [[Literature/{{Lensman}} Sergeant VanBuskirk]] and [[Literature/StarshipTroopers Corporal Juan Rico]], and they're equipped with dirigible space armor and weapons like recoilless machine guns, micratomic grenades, bazookas firing A-rockets, and [[AtomPunk nuclear-powered]] [[FireBreathingWeapon flamethrowers]].

Since SpaceIsAnOcean, Space Marines are the elite expeditionary troops carried by spaceships, their roles paralleling those of [[SemperFi conventional]] marines: [[DropShip mobile deployment]] from the ship , [[BoardingParty boarding hostile ships]], securing ports -- including {{Space Station}}s -- from SpacePirates and enemy forces, and landing on hostile shores to secure a beachhead, although in this case, they land on enemy planets. These [[ProudWarriorRaceGuy
rough-hewn, tough warriors]] with [[SemperFi strong esprit de corps and fighting spirit]] are the frontline troops of choice for humans battling marauding aliens in the StandardSciFiSetting.
