What named creators run on Jäger, and every option the game allows. Plus the gadget interactions that decide the matchup.
Primary and attachments: NotJoeyBlack and Rasco100's pick. The secondary list is every option the game gives Jäger; 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.
Thatcher's E.G.S. Disruptor disables a deployed Active Defense System, letting a grenade through that it would otherwise shoot down.
The Candela releases its flash charges as a thrown grenade, and Jager's Active Defense System shoots it down before it lands, so Ying's entry tool never goes off.
Both barrels of the KS79 Lifeline fire a projectile, so an Active Defense System covering the doorway eats the concussion round and the impact round alike.
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.
Jäger 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 Jäger 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.
