Having them in your R6 Siege Operator pool is a good option. Let’s find out some details about the R6S best Operators 2025!

Denari

Denari is a disruptive defender introduced in R6S Year 10 Season 3: High Stakes, released on September 2, 2025. His unique T.R.I.P. Connector creates laser grids that slow, damage, and disable attacker gadgets. By linking multiple devices across doors and hallways, he denies entry routes and delays pushes, giving defenders time to rotate. His flexible loadout, including the Glaive-12 slug shotgun, allows both close-range power and site control, making him a key operator for area denial and strategic defense.

Dokkaebi

​Dokkaebi is a Korean best attacker operator in Rainbow Six Siege, who messes with defenders’ communication by forcing their phones to ring with her Logic Bomb. This forces defenders to stop and silence their phones or risk getting tracked. On top of that, she can hack downed enemies to access defender cameras, giving attackers a huge intel advantage.

Thatcher

Thatcher operates as a Support or Anti-Gadget Specialist, employing his EMP Grenades to disable defender electronic devices within their blast radius, thereby neutralizing gadgets like Mute’s Signal Disruptors and Bandit’s Shock Wire, and clearing the path for hard breachers and other attackers.

Nomad

Nomad uses airjab devices that repel incoming defenders, shut down flanks, and secure positions for her teammates. She’s not only a good attacker but also a whistleblower for her team, which makes her a valuable asset.

Zero

Zero uses piercing surface cameras that allow attackers to gain useful reconnaissance and the capability to shut down defender devices. He’s a true professional when it comes to his ARGUS Launcher, which launches cameras that stick to both easy-breaking and reinforced surfaces.

Ace

A high-level hard breacher with a utility device. His S.E.L.M.A. explosive gadget can breach reinforced walls, hatches, and even castle barricades, so he is flexible in his application. Coupled with the primary weapon AK-12, one of the top DPS rifles in the game for dealing damage, he is a solid pick for attackers. Ace’s safe long-range breaching ability allows teams to create key entry points without exposing themselves in the process.

Lion

Lion’s drone deploys scans that reveal the positions of moving defenders, providing real-time intel to coordinate team strategy and pin down foes. It’s a perfect opportunity for your team to plan an attack or try new strategies, so Lion is a valuable operator in the current meta.

A-Tier

R6S A-Tier attackers are solid choices that can have a significant influence, but also rely on team synergy or particular circumstances. They provide consistent utility and firepower but are less overpowering than S-Tier operators. But you still can achieve your Desired Rank without wasting your time on any operator with our help!

Ram

Ram is a classic chaos agent who disrupts defender builds with her BU-GI Auto Breacher. Her deployable robot goes berserk on its own, destroying barricades, walls, and devices in its way. If you enjoy blowing up everything in your vicinity and disrupting defender positioning, Ram is a must-pick.

Thermite

Thermite is a powerful breacher, but close range is necessary for optimal impact. Though Thermite excels at breaching reinforced walls, he is not as mobile as Ace and is, therefore, less sought after on pushy rounds. His charges leave big holes, which are ideal for coordinated team pushes.

Brava​

Brava in Rainbow Six Siege disrupts defender compositions by exploiting their devices with her Kludge Drone, switching them to the attacker’s side. She’s perfect for counterplay against defenders who rely on deployable devices like Valkyrie and Maestro. When defenders are relying on deployable devices, Brava can completely ruin their strategies.

Blackbeard

Blackbeard, an operator who wields a shield attached to a rifle, gives front cover in battle, enabling him to attack defenders at less danger.

Hibana​

Hibana is a breacher operator with ranged capabilities who can breach reinforced walls and hatches using her X-KAIROS explosive pellets. She is superior to Thermite in the aspect that she can open angles at a distance, keeping her safer from defenders pushing on her. She’s a pick that can shine in both slow and aggro attacks.

Jackal​

Jackal tracks roamers by reading their footsteps via his Eyenox Model III, mapping them for the entire team. Defenders can either remain concealed or keep moving to prevent being scanned. If your team is experiencing roamer issues, Jackal is a simple fix.

Sledge

Sledge is a trusty soft breacher with a strong gun and grenades. His ability to open vertical angles with his hammer makes him a game-changer for map control. The L85A2 is a solid gun, and his frag grenades offer extra versatility for clearing defender utility. Sledge’s versatility shines on maps with destructible floors, where he can use vertical play to pressure defenders without a direct engagement. His capacity to hold positions of importance while simultaneously disrupting defender compositions at the same time cements his place in every competitive and ranked game. He is also a very good counter to shield operators, as his hammer can destroy them instantly, nullifying threats such as Clash or Montagne.

Zofia

Zofia in Rainbow Six Siege uses a grenade launcher that is capable of firing impact and concussive rounds, enabling her to stun defenders and blast soft surfaces efficiently.

Ash

Ash is a mobile entry fragger with aggressive gadgets who excels at quick breaching and opening up new avenues into objective zones.

This enables her to quickly tear apart the defender positions and keep up the pressure of attack for her team.

Montagne​

Montagne is a French attacker with a full-shield tank that can deploy his shield for maximum frontal coverage. He excels at blocking line of sight, defender bullet soaking, and escorting teammates safely into the site. Properly played, Monty gets defenders using utility just to move him out of the way.

Grim​

Grim is all about space control with his Kawan Hive Launcher, which deploys tracking nanobots on defenders caught in his space. His bees don’t kill, but they make defenders reposition or receive pings constantly. He’s fantastic at flushing anchors and shutting down rotations.

Maverick

Using his blowtorch, Maverick creates tiny holes in armored plating, creating new lines of sight and points of entry without alerting the defenders. This R6 Siege operator is a strong A-Tier attacker, especially in a coordinated team.

B-Tier

B-Tier attackers in R6 Siege Y10S3 are good options that can perform nicely but have glaring issues or superior substitutes. They can still be useful to your Rainbow Six Siege X team but might need particular strategies to be effective.

Finka

Finka sits in B Tier in Rainbow Six Siege X because her kit, while solid, has become less impactful in the current meta. Her global heal and recoil boost can still clutch rounds, especially for aggressive pushes, but they’re no longer as dominant since defenders have more ways to counter team-wide buffs. She’s still useful in coordinated teams, but less effective for solo queue or high-level coordinated play compared to other entry or support operators.

Flores

Flores uses explosive drones, which can blow up defender gadgets and barricades, creating openings and breaking up defensive setups.

IQ

Ying

Ying’s Candela devices fire a series of flash charges, blinding enemies and enabling aggressive pushes into contested zones.

Deimos​

Azami

Japanese operator Azami utilizes the Kiba Barrier, a throwable kunai blade that deals solid damage to attackers and, upon impact, opens up into a circular concrete shield. The shield is bulletproof but can be demolished through the use of explosives, close quarters, or other equipment, such as Sledge’s hammer.

Clash

Despite being one of the most polarizing defenders, Clash has found a strong niche in the current Rainbow Six Siege X season. Her shield allows her to stall pushes, block chokepoints, and delay entry with ease, especially in narrow or hallway-heavy sites. Paired with intel operators or trap-heavy comps, she becomes even more frustrating to deal with, making her a solid pick for coordinated teams looking to disrupt attacker pacing.

Kaid

Kaid in Rainbow Six Siege uses the Rtila Electroclaw, which is a thrown device that electrifies reinforced walls, hatches, and the barbed wire around it to deter breaching. As an all-purpose defense that can deny several surfaces using a single gadget, he is highly effective. For combat versatility, Kaid wields the AUG A3 submachine gun and TCSG12 shotgun.

Mute

Installation allows defenders to monitor and thwart intruders attempting entry into fortified strongholds.

Aruni

Aruni makes use of Surya Gates laser terminals at doors, windows, and hatches to defend against attacker infiltration by destroying and immobilizing their equipment. Her gates are recyclable when used to fire and will require the attackers to consume utility or health to bypass them. Aruni’s multi-tool equipment, like the P10 RONI submachine gun and Mk 14 EBR marksman rifle, complements her defensive gaming.

A-Tier

A-Tier defenders are good selections that offer great utility and defensive support but might need to be properly positioned or have teamwork in order to reach their maximum potential. They are trustworthy picks that can be played under most circumstances.

Echo

Echo’s drones are also capable of turning off informative real-time streams and can be moved to position them where they can do the most coverage. Deployables and MP5SD are part of the loadout that Echo has, which makes him an effective anchoring operator.

Fenrir

Fenrir deploys the F-NATT Dread Mine, a launcher whose explosion releases a debilitating gas that disrupts the sight and movement of attackers. Strategic placement of these mines at entry points has the potential to disable attacker mobility and allow defenders a chance to take advantage of the blindness of the attackers. Fenrir’s equipment is the MP7 submachine gun and the bulletproof camera, which complement his defense and intelligence roles.

Kapkan

Kapkan uses Entry Denial Devices (EDD), explosive traps set on door and window frames that explode when activated by the attackers, crippling and even killing them. Kapkan’s traps have the effect of slowing down and hindering the advance of attackers and making them cautious. Kapkan has the 9x19VSN submachine gun and the SASG-12 shotgun, both of which can be used efficiently in a variety of defensive positions.

Lesion

Lesion deploys GU Mines, undetectable proximity-fused mines that poison and incapacitate attackers upon activation. The mines hinder attacker movement and give audible warnings to defenders of enemy presence.

Melusi

Uses Banshee Sonic Defense units, which project a slowdown field on the attacking players around them, decelerating their movements. Her devices act as warnings and disrupt the attacking players’ momentum.

Mozzie

Mozzie can deploy Pest drones to strike and quiet aggressor drones, using their spy equipment against them. His ability disables aggressor scouting and gives defenders more intel.

Tubarão

Can move underwater paths with water drones, which introduces surprise flanking and attacking. His unorthodox play style disrupts the defender’s expectations and opens up new attack possibilities.

B-Tier

B-Tier defenders are middle-of-the-pack picks with good gadgets or guns but have trouble against more powerful attackers or require out-of-the-box setups to shine. They can be good for the team defense, but lack the consistency of operators from the top tiers.

Bandit

Blinds, hardened walls, barbed wire, and deployable shields with Shock Wire devices discourage breaching attempts. His aggressive gaming style can hamper attacker strategies by denying entry points.

Castle

Protect windows and doors with bulletproof barricades, limiting attacker entry and lines of sight. His utility makes attackers waste resources or change tactics.

Frost

Sets Welcome Mats, mechanical traps that disable attackers who trigger them, providing opportunities for defenders. Her traps penalize sloppy attackers and can shift the momentum of a round.

Maestro

Uses Evil Eye cameras, bulletproof tools with high-powered lasers to scan and blow away attackers. His devices offer him real-time feedback and can blow up attacker devices.

Pulse

Employs a Heartbeat Sensor to track aggressor heartbeats on the ground, revealing where they are. His scouting enables ambushing and surprise attacks.

Skopós

Uses cutting-edge optics to observe and tag assailant movement and transmit real-time information to fellow operatives. His scouting power improves the level of coordination and readiness reaction among his unit and allies.

Solis

Solis is a Colombian operator and an intel-gathering monster in Rainbow Six Siege, with a good defensive gadget that counters incoming drones. Solis’s SPEC-IO Electro Sensor is a nightmare for attackers and enables her to scan for attacker gadgets, so she is a priority pick when it comes to countering drones and gadget-based teams. Solis is great at intel-gathering and foiling the plans of the enemy with her mobile playstyle and powerful P90 or ITA12L shotgun.

Solis can detect and remove drones before attackers can get valuable information, strongly disrupting their early-round strategy. Her ability to detect hard breaching tools like Thermite’s charges or Ace’s S.E.L.M.A. devices also allows defenders to react ahead of time, so she is a valuable asset when it comes to defending reinforced locations.

Vigil

Protects cover by activating the ERC-7 device to become invisible to enemy drones, making it more difficult for them to find him when establishing and performing an action. This enhances roaming effectiveness by leaving attackers in doubt about their location.

Warden

Activates Smart Glasses to penetrate through smoke grenades and fend off flash attacks, seeing clearly. His power negates attack plans utilizing covert vision.

Alibi

Caveira

Uses her Silent Step to get close and catch enemies off guard, using it to interrogate fallen enemies and know the positions of her enemies. Her playstyle is stealth and high-risk-high-reward.

Doc
