What named creators run on Mira, and every option the game allows. Plus the gadget interactions that decide the matchup.
Primary and attachments: NotJoeyBlack and Rasco100's pick.
Rainbow Six counters are gadget interactions, rules of the game rather than statistics, so every pairing here comes from the two operators' own kit pages: the mechanism from whoever wins it, the gadget it beats from whoever brings it.
A Black Mirror is carved into a wall and then defended, and Kali's lance lodges in exactly that wall and destroys gadgets in its radius, so the one-way window goes without anyone entering the room.
A Black Mirror gives Mira a protected sightline to trade from. Blackbeard's H.U.L.L. Adaptable Shield gives him a protected sightline onto the same lane, so the trade she set up is the one she cannot win.
A Black Mirror is worth exactly the sightline it opens. The R.O.U. Projector System drops a screen across that line, so Mira keeps the protected window and loses the view through it.
Nokk's HEL hides her from drones, bulletproof cameras and Evil Eyes, which are observation tools. A Black Mirror is a pane of glass with Mira's own eyes behind it, so the cloak has nothing to hide from.
IQ's Electronics Detector finds devices through walls. A Black Mirror is laminated glass with no electronics in it, so she walks the lane it covers without the warning she is used to.
Mira is a Defender in Rainbow Six Siege.
Rainbow Six's counters are mostly deterministic gadget interactions, rules of the game rather than statistics, so we state them from the two operators' own kit pages with no telemetry needed. A pairing is only written where the winning operator's page names the mechanism, which is why plenty of operators here carry none. Statistical data is based on external APIs and publicly available information. It may differ from official data.
NotJoeyBlack, Rasco100 and SINOOS publish loadout picks under their own name, and this page credits each of them rather than averaging them into a single answer. We measure nothing ourselves. The list of what Mira can equip is the game's own, and is separate from anyone's opinion about it. Statistical data is based on external APIs and publicly available information. It may differ from official data.
