** If a teammate tears down one of Castle's barricades for whatever reason, Castle regains it back in his inventory, despite the animation showing the armor panel being completely destroyed.

** On Plane, the one room designated "toilet" is empty save for a ladder to the server room upstairs.

** If a teammate tears down one of Castle's metal barricades for whatever reason, Castle regains it back in his inventory, despite the animation showing the armor panel being completely destroyed.

* AllThereInTheScript: The real names of the operators are never mentioned in an actual match. You can only find them in the operator bios on the operator page, or on [[TheWikiRule the Rainbow Six Wiki]].

** Your operators' actual armor rating, which is on a three-point scale, generally means a difference of one or two bullets depending on the weapon. However, Rook's Armor Pack ability allows additional resistance of about four or five extra bodyshots. It's useless in medium skill play, where everyone gets headshots, but vital in both low and high skill where nobody either has the skill or gets the chance.

* ColorCodedForYourConvenience: Drones and Cameras will change color based on who's controlling them at the moment. Those controlled by the Attackers flash yellow; those controlled by Defenders flash blue. This also extends to team-centric gadgets, such as the lights on Nomad's airjabs and Jager's ADS.

** On April 15, 2021, Smoke and Mute received bundles turning them into [[WesternAnimation/RickAndMorty Pickle Rick and a Gromflomite]] respectively.

** Run-outs as a Defender, which can be done in conjunction with a barricade trick to surprise Attackers. A well-executed run-out can allow you to gun down unexpecting Attackers very easily, especially if they're busy rappelling or droning the map for your teammates, but flunking this maneuver will just get you shot.

** [=ACOGs=] being a coveted item for Defenders, especially Jager, was acknowledged in M.U.T.E. Protocal with a giant ACOG hologram in one of the rooms.

* GameBreakingBug:

** The discovery of a Clash glitch in mid-2019 essentially divided the fanbase with the two factions - people who exploited it and people who hated it. Ubisoft eventually disabled Clash gamewide until they could issue a fix for the glitch. Unfortunately, history repeated on December 12, 2019, when the discovery of another glitch forced Ubisoft to disable her ''again''. She was re-enabled on January 10, 2020.[[RunningGag And then disabled on February 21, 2020, where she still remains now.]]

* GradualGrinder:
** Defending Operator Smoke has special Gas Grenades that can down and kill enemies quite quickly if they can't leave the area of affect. This is especially effective against Slow Operators like Fuze, where they can't get out of the poisonous fog quick enough.
** Capitao, Goyo and reworked Tachanka have incendiary gadgets that blanket an area in fire, dealing damage over time to anyone in their area of effect.

** Impact Grenades are available to the Defenders, and while they deal less damage, they'll create openings cleanly and relatively efficiently. [[GradualGrinder Smoke]], [[JackOfAllStats Castle]], [[MightyGlacier Rook]] and [[MechanicallyUnusualClass Caveira]] are some of the more common users of this gadget.

* TheStoic: ''Everyone''. While characters do have quotes, there is a very high chance where they will simply stay silent, giving few hints to their less stoic personalities. In fact, the people who talk the most in this game are probably the White Mask AI enemies. {{Justified}} since Rainbow is an elite unit of professionals.
* StoneWall:
** The Attacking Operators Montagne and Blitz (Along with the Recruits) wield specialized Ballistic Shields and are generally the most heavily armored of the attackers, but are limited to pistols as a result.
** Defending Operators Echo and Clash play a far more defensive approach compared to the other Heavy Armored Defenders. While they do still have decent firepower, these Defenders are better suited to support roles due to their gadgets and loadouts.

* CompetitiveMultiplayer: Outside of Situations and Terrorist Hunt, all of the game modes are 5v5 player versus player. It is also worthy to note that there are two matchmaking lobbies, Casual and Competitive, with Competitive rounds being 1 minute shorter.

* {{Hammerspace}}:

* HelmetsAreHardlyHeroic: Many of the Operators by default don't wear any helmets, not like they provide any additional protection in-game. The rest are either wearing hats or balaclavas or are just bare-headed.

* FriendlyFireproof: Fully averted, and you can injure or even hose down your teammates and hostages if you so choose. However, doing so enough times will activate Reverse Friendly Fire on you (and in the case of a hostage being killed, immediately ends the round for your team as a loss), after which point any further damage dealt to friendlies will be inflicted upon you instead (or in the case of a gadget-sourced damage, the device itself will be destroyed). This persists until the match is over regardless of how many rounds it takes. If you were the one being killed by friendly fire, you will get the option to confirm the act as intentional griefing, or forgive it as an accident, which may or may not result in the offender being forcibly kicked from the match the next time they repeat it.

Available from August 4th to August 24th, 2020, M.U.T.E. Protocol takes place on a [[{{Zeerust}} retrofuturistic]] version of Tower. Attackers are tasked with securing two out of three servers from the Defenders with no drone phase - the Attackers ARE the drones! Attackers dematerialize when they enter their drones and rematerialize where their drones were when they exit. Defenders can use a network of bulletproof cameras to teleport around the map and can add to the network with their own cameras.

A co-op {{Spinoff}} game called ''Rainbow Six Quarantine'' was announced at E3 2019, and is set to release in 2020.

* ConcussionFrags: Interestingly, both subverts this trope and plays it straight; Frag grenades will damage the environment in a realistic way, leaving a consistent pattern of shrapnel holes in surrounding walls just like a real frag would, but in terms of damage it behaves the same way as in other games, only doing damage within a limited radius and not via shrapnel. Hence, the grenades behave like frag grenades relative to the environment, and concussion grenades relative to the players.
* CoOpMultiplayer: Terrorist Hunt is the co-op mode of the game, though it receives far less attention in comparison to the competitive modes. Bomb, Hostage Protection, and Hostage Extraction are available modes, slightly modified from multiplayer modes to accommodate for AI behavior, and there is also the Terrorist Hunt Classic mode, where the objective is to simply kill all terrorists. In addition, Article 5, the final "Situation", is also a co-op game of Terrorist Hunt Bomb, and it is possible to be matched up into one when searching a Normal difficulty game with the Bomb mode enabled.[[note]]The mission is technically a round of Terrorist Hunt - Bomb on the Bartlett University map (just gassed up), though it is worthy to mention that the multiplayer map was a cleared-up version of the originally Situations-only map and released far later.[[/note]]
* CommonTongue: Even though Team Rainbow is an international team, all Operators in game use English, with the occasional GratuitousForeignLanguage popping in a few times here and there and in some Operator trailers. [[JustifiedTrope This makes sense since having everyone speak their mother tongue would severely mess up communication]].
