What named creators run on Deimos, 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.
Deimos commits to one tracked target with only the .44 Vendetta available, and an F-NATT Dread Mine takes his vision during exactly that commitment.
Deimos reveals his own location the moment he starts tracking, and Skopos is watching two rooms at once, so the reveal lands wherever she happens to be.
Deimos picks a target and his probe reveals their location, which is the one thing Caveira's Silent Step is built to deny. His own page notes it reveals him too, so she gets the fight she wanted, just not the ambush.
Deimos 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 Deimos 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.
