* AllThereInTheManual: While all the operators look like TheStoic at a glance, they actually have distinct backgrounds and personalities that you can only read in their bios in the operator screen. Or the [[TheWikiRule Wiki.]]

* BalanceBuff: As with any competitive multiplayer game, characters and game mechanics are frequently tweaked.
** To combat the increasing precedence of attackers having an advantage over defenders, Ubisoft gave six defenders [[note]] Frost, Doc, Mute, Castle, Caveira and Vigil[[/note]] a new Bullet Proof Camera. It's a non-rotatable square-shaped camera that can be drilled onto surfaces and used to monitor hallways. It's main gimmick is in the name, as it cannot be destroyed from the front and must be taken down either with explosives or a hit from the side, where it's still vulnerable. It also has heat vision, allowing it to more easily pick out attackers in the environment and see through smoke grenades.

** Bank and Favela have no bathrooms. Most maps just have one that is unisex even in contexts where they should be segregated, such as the nightclub in Coastline.

* CloseRangeCombatant: Anyone choosing to wield a shotgun as a primary weapon is necessarily this.

The S.I. 2021 playlist contains much of the same, but this time Stadium has been reconfigured to be a combination of Border and Coastline. Cosmetics are tied to a 100-tier battlepass available since the beginning of ''Operation Neon Dawn''. Included with the event is the cinematic "The Playbook."

** BOPE wear black uniforms, FingerlessGloves, bare forearms, and berets with the BOPE logo on them.

** The map "Villa" is a raid on the "Vinciguerra Crime Family," the same one references in Alibi's bio. The Vinciguerras were the antagonists of the film ''Film/TheManFromUNCLE2015''

A co-op {{Spinoff}} game called ''Rainbow Six Quarantine'' was announced at E3 2019, and is set to release under the title of ''VideoGame/RainbowSixExtraction'' in 2022.

** Defending teams often designate specific players as 'Roamers', players who position themselves way outside of the objective area and try to flank enemies from behind, pick off enemies with guerrilla tactics, or at the very least disrupt enemy tactics. Roamers often use FragileSpeedster Operators such as Jäger, Bandit, and Caveira, providing high speed to outmaneuver enemies, though slower operators can be used to roam as well. In fact, all-out point defense is considered a bad idea since it surrenders the rest of the map, and Fuze will absolutely obliterate any attempts at doing it.

* LuckilyMyShieldWillProtectMe: ''Siege'' uses Ballistic shields more extensively then the previous games. In particular, Montagne has a ballistic shield called "Le Roc" (the rock) that can expand to cover his entire body and pretty much makes him (and the teammates behind him) invincible from the front. Since the ''Dust Line'' update, Montagne's Shield received a significant buff in the form of side panels. These allow him to be an even better pointman, since his shield can protect him much better now as he previously left his flanks easy to shoot at. Other Operators who use shields include Blitz, who can use a custom Flash Shield that can blind enemies akin to flashbangs, and Fuze and the FBI Attacker Recruit, who both have more standard shields.

* MultinationalTeam: More heavily emphasized than previous games and mostly enforced. Without using recruits to fill up the ranks, it is not possible for either side to consist entirely of Operators from a single country, since there are at most 2 operators of a single CTU from one country on one side, and there are only 6 [=CTUs=] that are from the same country. Specifically, the FBI have attackers from Delta Force and the Navy [=SEALs=], the GIGN now have a third attacker through CBRN, as do the Spetznaz, and the SAS have a third british defender in the [=SCO19=].

* ReinforceField: The defenders' Wall Reinforcement works like a non sci-fi version of the trope. The Wall Reinforcement is a folded-up metal wall, deployed to the ground near the destructible wall folded up ([[AcceptableBreaksFromReality its length conveniently fits the wall's size or a perfect fraction of it]]), and the defender pulls it up to chest height, then operates a lever which in one motion pushes the upper half to the top and with another motion secures the metal wall to the destructible wall with piston-operated pins. The resultant wall is indestructible to bullets (though taller walls leave a destructible section at the top, since the height of the metal wall stays constant) and can only be destroyed by Thermite and Hibana's exothermic gadgets or Maverick's blowtorch.

** When Rook has his Elite skin on, his [[https://www.reddit.com/r/Rainbow6/comments/9inxyk/i_just_noticed_that_on_rooks_elite_set_it_says/ armor pack has a folder]] that says "Operation Rook Mine", referencing the [[https://www.reddit.com/r/Rainbow6/comments/4j29mp/got_team_killed_when_i_asked_why_this_was_his/ meme]] where a player was [[IfICantHaveYou teamkilled for taking Rook]].

* CharacterClassSystem: The Operators can select one of two secondary gadgets available to them (selected from a pool of side-restricted gadgets) and one out of a few weapons available to them (selected from a pool of side-restricted CTU-specific weapons), and each get their own special Operator gadget, which tends to define their role the most. Recruits can select weapons from several CTUs (though still restricted in combination, such as being unable to use a Defender weapon as an Attacker), and get a second secondary gadget in place of their operator gadget (such as being able to take both breaching charges and a grenade).

** Ash received an Elite Skin dressing her up as classic [[VideoGame/TombRaider Lara Croft]].
** Zofia received an Elite Skin dressing her up as classic [[VideoGame/ResidentEvil1 Jill Valentine]] for Resident Evil's 25th anniversary.

* RealityEnsues:
** Fuze's gadget, a breaching charge that launches grenades into adjacent rooms, is not at all practical for hostage missions, and is known to [[NiceJobBreakingItHero kill the same hostage his team is trying to save]].
** PlayedWith with headshots. While Operators can take a few shots and survive, a single head shot will kill anyone no matter what. Although, in cases where an Operator is wearing a helmet, it doesn't exactly make any particular sense how the helmet [[ArmorIsUseless won't protect the head against a 9mm bullet through a thin wall, from a long distance away]].

* TwentyMinutesIntoTheFuture: The game apparently takes place a little into the future (no specific dates are given), since Rainbow is equipped with technologies that are a little more advanced than what we have currently. The Skyscraper map even has a holographic table in one room.

* ArtificialStupidity: The terrorist bots are known for being braindead on occasions, especially the one with the pistol and shield, which can occasionally kill themselves using the thermite charge. Other times, his pistol can instantly kill the hostage, resulting in an instant loss. They also stand right in the open when fighting players and never sprint.

** If a teammates finishes off a player you downed, you actually get more points (50 from the down plus 75 from the kill assist versus 100 for killing them yourself) to alleviate the frustration of a KillSteal. This was later changed to a player receiving the full 100 for killing or injuring while the player that finishes them off gets the assist score.

** When a cheater gets banned, every match they partook in gets voided, reverting any MMR gained or lost for playing with them.

* UnusableEnemyEquipment: No one can pick up anyone else's dropped weapons, though some shotguns and sidearms are available for Operators of the same CTU on both sides. Some of the gadgets like Rook's body armor and Tachanka's LMG can be be used by the opposing team if they manage to get their hands on it while it is deployed.

** Since there are two layers of walls, it is possible to make a variety of weird killhole angles. Some tactics include using a low-power gun to shoot a tiny row of bullet holes that are virtually invisible at the other side, and shooting the wall at an extreme angle, creating two displaced holes that look largely intact at a glance but still provide an angle to a desired spot.

** Tachanka pulls out a machine gun with a chest-high tripod straight out of his pockets. Yes, a meter-long machine gun with a chest-high tripod.

* QuickMelee: Melee is done by a quick press of a button. It kills/downs enemies in one hit, though most of the time it is used for punching holes in walls.

* MilitariesAreUseless: Averted with the New Mexico National Guard units, which were deployed to seal the area off and assist RAINBOW forces in securing the perimeter.

* CallForward: The Smasher's mechanics of smashing through walls and knocking operators back (potentially through walls as well) were recycled for Nomad's Airjabs and Oryx's Remah Dash.
* NoEnding: After [[spoiler: retrieving the Soviet-era capsule that sparked off the whole mess]]... that's it. There's no word on its aftermath, and the entire incident is never mentioned in any form, ever again. Well, not until ''Quarantine''.
