What named creators run on Grim, 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.
Grim fires the Kawan Hive into a room and follows the intel in, and a Yokai holding that room disorients him at the doorway the swarm marked.
Oryx's Remah Dash is about crossing ground faster than anyone can react. A Kawan swarm on the rotation tags him every time he uses it, so the speed stops being surprise.
Vigil's ERC-7 wipes his image from cameras. Grim's bots do not watch him, they stick to whoever walks through, so the cloak has nothing to hide from.
Grim 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 Grim 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.
