Lesion is considered one of the best trap operators in Rainbow Six Siege. Here’s a full guide on how to use his weapons and Gu mines effectively.

Rainbow Six Siege, a tactical first-person shooter developed by Ubisoft, has experienced tremendous growth throughout the years that it has existed. The game is still receiving constant updates to improve the experience and change the meta to keep things fresh.

Lesion: the 2-speed, 2-health defender was introduced in Y2S3 Operation Blood Orchid alongside Ying and Ela. This defender from Hong Kong is one of the strongest defenders in the game in terms of both utility and gun power. So, when picking this operator, here are some of the things you should know.

Lesion Operator Guide


“Make no excuses for who you are. Only the weak-minded will demand you make yourself smaller.”

Born and raised in Tseung Kwan O (Junk Bay), Liu’s early years were spent working alongside his father in the shipyards, stripping obsolete tankers for raw materials and parts. Growing up surrounded by hazardous materials and seeing their long-term effects on his fellow workers left Liu with an abiding respect for toxins and their effect on the human body. Initially seeking additional income, he volunteered for mine clearing duties in Yunnan and Guangxi provinces where his abilities and bravery caught the attention of key personnel within the Hong Kong Police Department. Liu then joined the Explosive Ordnance Disposal Bureau (EOD), giving him the opportunity to continue his chemistry and forensics-based education along with intense on-site training. Liu’s expertise with chemical, biological, radiological, and nuclear threats made him a clear first pick during the formation of Rainbow’s CBRN unit. Liu continues to volunteer for mine clearing duty in his spare time.

Liu continues to live close to where he grew up. His connection to the location is more than nostalgia. There’s a sense of satisfaction in knowing what it used to be and how time has affected it. Liu says both he and Junk Bay have changed for the better, and that the future can always be shaped into something good.

As he did at the start of his career, Liu still volunteers in underprivileged areas. His expertise has contributed to the clearing of tens of thousands of mines and unexploded ordnance. In particular, he’s been consulting the tech experts within Rainbow as he and operators Olivier “Lion” Flament and Lera “Finka” Melnikova look to incorporate state-of-the-art solutions into their CBRN threat unit.

Best Weapon Loadout

  • Primary Weapon: T-5 SMG (SMG), SIX12 SD (Shotgun)
  • Secondary Weapon: Q-929 (Handgun), SUPER SHORTY (Shotgun)
  • Secondary Gadgets: Bulletproof Camera / Impact Grenade
  • Unique ability: GU MINES

Lesion has the option between the T-5 SMG and the SIX12 SD Shotgun to pick as his primary weapon. The T-5 submachine gun boasts a rapid rate of fire and decent damage output, coupled with a recoil that’s not that hard to control. But because of its high fire rate, controller players should practice with it a bit to get a feel of the recoil. As Siege has a one-shot-headshot mechanic, the high fire rate will massively help you land the killing blow. Nevertheless, it’s important to note that this firearm lacks a magnifying scope, so you’ll need to select a 1x optic of your preference. When it comes to attachments, our recommended choice is the compensator and vertical grip.

Conversely, the M870 shotgun can also bring some significant firepower. It finds its strength primarily in close-quarters combat, making it ideal for anchoring within the site and holding tight corners effectively. Holding angles will be more effective since the latest patch, as ADS with shotguns tightens their spread even further now. While a shotgun equips Lesion with the ability to reshape bombsites by creating essential openings and angles. However, it’s worth noting that the Lesion now has another secret in his sleeve which is the Super Shorty secondary shotgun. Therefore, our recommendation for the primary weapon leans toward opting for the T-5 SMG. This choice not only offers flexibility in engaging enemies at various distances but also enables you to adapt to a wider range of combat situations, be it long or short-range engagements.

As we stated above, with the recent Y8S3 patch, Lesion now has the Super Shorty as a secondary weapon. We strongly believe you should pick this weapon over the Q-929 pistol. The shotgun allows you to reshape the map, creating important rotations and lines of sight.

Secondary Gadget

Lesion can pick Impact Grenades or the Bulletproof Camera as his secondary gadget. While the impacts have been a staple choice for many Lesion players over the years, we will now lean towards suggesting the BP camera. The obvious reason for this is that Lesion can now bring the secondary Super Shorty shotgun, and the BP camera can also provide valuable intel for the whole defense.

Unique Ability

Lesion’s primary gadget is called Gu Mines,” commonly known as ‘Lesion traps.’ This trap gadget has needles inside that deal damage to Attackers if they step foot near it. These mines for a long time had cloaking ability, which has been removed by Ubisoft recently with the Y8S3 update. Now these mechanical poison mines are not visible, but they do have an initial damage of 5hp.

The victim of the trap will continue to be affected by a gradual loss of health until they are downed or the needle is removed. After every 2 seconds, the poison timer will tick and it will deal 12hp damage until the Attacker takes the time to remove it. With the needle inserted, the Attacker won’t be able to sprint or plant and will make a grunting noise that will alert the defenders.

Unlike Ela mines, Lesion’s Gu mines are only throwable on horizontal surfaces, as they don’t possess any sticking ability. These Gu mines slowly generate throughout a round, similar to Wamai’s disc, so try to stay alive till the end to get the maximum 9 mines.

Tips and Tricks

(i) Place the Gu Mines strategically, such as near common plant spots. This will prevent the planter from defusing the bomb, and if the timer is running out, the Gu mine can win the round.

(ii) Lurk near a Gu Mine to get a kill when the Attacker steps into it and is busy removing it. However, stay alert not to get baited by the Attackers instead.

(iii) Attackers don’t need to directly step foot on a mine, as it has a certain area of effect. So, you can place a mine tightly near a doorway so it is not easily visible to the Attackers.

How to counter Lesion?

As Lesion mines are not invisible now, you can easily shoot the traps as an Attacker. As the gadget has been turned into a mechanical device from an electric one, it is unaffected by EMPs and IQ’s scanner. But Twitch’s drone is still an effective way to clear out all the traps before you enter the map.

Should you pick Lesion?

Lesion is one of the best flex operators in Rainbow Six Siege with a good loadout and an effective gadget. The Gu Mines are a great trap to slow down a fast Attacking push. Lesion is a flex operator, so when you pick him you will have the freedom of choosing to roam or anchor in the site. It will require some experience to know how to get the most use of these GU mines. Additionally, as the GU mines recharge over time, you need to stay alive as long as possible. Patience is key here, so if this fits your style we highly recommend in using this operator.
