What named creators run on Lesion, 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.
Gu mines are hidden on the floor and are only dangerous to someone walking in. A Fuze cluster charge covers that floor in a fan of explosions before anyone does.
Ram's BU-GI Auto Breacher grinds along a set path destroying every device in it, and Lesion's Gu mines are on exactly that floor.
Jackal roams to follow footprints, which means covering ground on foot. Gu mines punish exactly that: they inject a toxin, they slow, and they are hidden where he is looking down.
A Finka boost restores health once, and a Gu mine keeps ticking and keeps him slow after it, so the heal buys distance rather than removing the problem.
Lesion 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 Lesion 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.
