History Series / TheExpanse

** [[spoiler: Dresden]], the MadScientist who massacred [[spoiler: all of Eros]] ForScience.

** The planetoid Eros jams the radar, leaving only visual observation possible from a nearby ship. Eros is about ten miles wide and can be easily seen by a telescope. It was first seen from Earth in 1898.

* {{Foreshadowing}}: The Blue Falcon Hotel's name is a big clue as to what will happen there. See MeaningfulName below.

** Earth's RailGun {{Kill Sat}}s fire a bullet that breaks into a spread of shrapnel once it nears the target, similar to buckshot except the bullet waits until the majority of the pellets will hit[[note]]This type of ammo is called [[https://en.wikipedia.org/wiki/Canister_shot canister shot]] and has been around [[OlderThanRadio since the 18th century]][[/note]].

** Mars has planet killer ships as a last-resort weapon which each carry ten missiles. Each missile can break apart into a spread of nukes that can blanket Earth if necessary[[note]]also called [[https://en.wikipedia.org/wiki/Multiple_independently_targetable_reentry_vehicle MIRV]] warheads in RealLife; the majority of today's strategic nuclear missiles work like this[[/note]].

* TimeForPlanB: When ''Rocinante'' is flagged for a ''very'' unwanted inspection in "Windmills", Naomi and Alex scramble to unlock the correct SpySpeak to call them off while Amos calmly heads down to the weapons-locker to prepare Plan B: trying to shoot anyone who comes through the airlock.

** Warships continue to use oversized gatling guns for point defense and close quarters combat alike. Since only battleships appear to be capable of mounting the much more powerful [[MagneticWeapons railguns]], any smaller class of warships lays down a dense hail of armor-piercing bullets instead that usually kills the target ship's crew without dealing critical damage to the ship itself.

* NoRangeLikePointBlankRange: Void battles between vessels below battleship tonnage tend to happen at distances of only a couple hundred meters, maybe about one kilometer at most, with both sides hammering each other with manually aimed [[GatlingGood gatling gun barrages]]. Victory seems to revolve mostly around which crew manages to not get shot to pieces last.

* NoGoodDeedGoesUnpunished: Answering a DistressCall is one way to get LuredIntoATrap.

* PoweredArmor: Certain Martian Marine Corps units are issued powered armor. By itself, the Martian suit is shown to be about as strong as a very physically fit individual, thus greatly magnifying the wearer's strength. The training exercise at the start of "Safe" also shows off some of its other goodies, like an ArmCannon, [[ImmuneToBullets immunity to bullets]], and a guided missile launcher in the backplate. The suit is also shown to require constant maintenance and support staff are required to help a marine put it on. Marines on standby will wait around in their undersuits to save on time in case they are ordered into battle.

* GermanicEfficiency: The Martians fit the bill. Their technology is top-notch, their soldiers are stoic and expeditious, and their complex infrastructure is implied to be a marvel. This makes sense for a culture whose only prerequisite is the resolve to commit their lives to turning a lifeless rock into a garden.
* GatlingGood: Warships continue to use gatling guns for point defense.

* MagneticWeapons: The ''Donnager'' has turret-mounted railguns while the stealth ships have spinal-mount railguns, and are apparently the smallest ships to have them.
