What named creators run on Ash, and every option the game allows. Plus the gadget interactions that decide the matchup.
Primary and attachments: NotJoeyBlack and Rasco100's pick. The gadget list is every option the game gives Ash; nobody we read picks between them.
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.
Mute's own page names Ash: the GC90 Signal Disruptor stops her M120 CREM Breaching Round detonating, so the ranged soft breach she is built around does not happen.
Ash's M120 CREM Breaching Round is fired across the room to open a wall from range, and that flight is exactly what an Active Defense System exists to end.
The Mag-NET System attracts Ash's M120 CREM Breaching Round away from the wall she aimed it at, so the hole opens where Wamai placed his gadget instead.
A Castle Armor Panel is meant to cost the Attackers utility at a door. Ash's M120 CREM Breaching Round takes it off the frame from across the room, at no risk and no approach.
The Banshee is bulletproof, so it survives rifle fire and not an explosion, and Ash can destroy it from outside the radius where it would have slowed her.
Ash is an Attacker 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 Ash 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.
