Military Science Fiction is a subgenre of both Science Fiction and Military Fiction, commonly sliding into the Space Opera territory. At its most basic, Military Science Fiction is Science Fiction that focuses on the military, but the genre has more specific nuances than that.
The Protagonist in this genre is normally part of the chain of command (or becomes part of it in progress), while an ensemble cast is The Squad. The story is usually set against the backdrop of a large-scale (space) war but war is optional. Instead, the story may focus on a Space Cadet Academy or a beleaguered garrison on a Bleak Border Base.
The Science Fiction part mostly manifests in futuristic weaponry and vehicles (first of all, Cool Starships), while the organization structure is mostly based upon contemporary US or Commonwealth military. It should come as no surprise that a high percentage of MSF writers are military veterans.
Often, the writers would cheat a little by having a Mildly Military organization instead of realistic military for the sake of good story. One particular subgenre of MSF in Video Games is A Space Marine Is You. Another that's especially particular (but by no means exclusive) to anime is the Real Robot Genre.
The acronym MSF may also refer to Mundane Science Fiction, a generally unrelated genre of sci fi.

Works with notable Military Science Fiction elements include:
- The Alien/Predator/AVP franchise(s) sometimes flirt with military science fiction, depending on the movie or work.
- Although the Alien series never involves warfare in its storyline at all, as they are more like monster movies set in outer space; however soldiers still end up serving as major characters in a few installments anyways.
- Aliens started the trend, with Space Marines (a very iconic fixture of military sci-fi) showing up to try and fight the titular Alien monsters.
- Alien: Resurrection takes place on a secret military research station orbiting over Earth.
- Alien 3: The Gun
- Aliens Extermination
- Aliens Armageddon
- Alien Blackout
- Aliens: Colonial Marines
- Aliens Fireteam Elite
- Aliens: Infestation
- Alien Trilogy
- Meanwhile the Predator series is much more consistently militaristic, with the protagonists in all but the second movie consisting mostly of experienced soldiers who are pitted in combat against the titular Predators, who are deadly alien warriors that enjoy hunting and killing other warriors.
- Although the Alien series never involves warfare in its storyline at all, as they are more like monster movies set in outer space; however soldiers still end up serving as major characters in a few installments anyways.
- Armorines: Project S.W.A.R.M.
- The Assassin's Creed franchise incorporates both military and sci-fi elements in its Assassin-Templar conflict storyline. The past segments usually have plots related to conflicts or other military-related events such as the Third Crusade and the Peloponnesian War with Isu technology and temples scattered throughout the world. The present segments also incorporate sci-fi elements as well with the protagonist reliving the lives of an Assassin inside the Animus, a virtual reality machine developed by the Templar-run Abstergo Industries.
- G.I. Joe.
- Gundam, pretty much every incarnation of it, except G Gundam, Gundam X, Model Suit Gunpla Builders Beginning G, and Gundam Build Fighters.
- The whole Halo franchise revolves around a galactic war between humans and aliens in the distant future.
- Mass Effect
- Resident Evil
- Space Battleship Yamato and her various spinoffs and adaptations, such as the live action movie and Space Battleship Yamato 2199.
- Stargate-verse
- Starship Troopers
- Star Trek drifts in and out of the subgenre; later entries in the franchise tend to make it more explicitly military, a tendency which its original creator violently opposed.
- Star Trek: Deep Space Nine is the most militaristic canon series.
- Star Trek Online is very militaristic, so much so that it took fan outcry to get the developers to patch diplomatic solutions into missions.
- Star Wars is obviously this; just as the title suggests, it's mostly about epic warfare in space. Many main characters are soldiers, diplomats, or both, and much attention is given to extensive battle scenes in all Star Wars movies and most other works.
- The Terminator franchise's backstory involves a post-apocalyptic future conflict, in which Skynet (a rogue military computer network) triggered a global nuclear war to destroy human civilization, and then deploys an army of killer robots in a genocidal war to exterminate the last human survivors. Skynet and the Human Resistance then both make frequent use of time travel in efforts to change the pre-war past (and thus the outcome of the future war).
- Wing Commander, particularly the novels by William Forstchen, and Wing Commander Academy.
- Argento Soma
- Argevollen
- Armored Trooper VOTOMS

- Magical Girl Lyrical Nanoha StrikerS, which takes the franchise's Gundam influences to its logical conclusion as the title character grows up to become a captain in Mid-Childa's military.
- Martian Successor Nadesico
- Neon Genesis Evangelion, though less so when the Alien Invasion premise began to play second fiddle to the psychology and introspection.
