Top 10 Best Operators in R6; 5 Best Attackers & Defenders

Since Rainbow Six Siege characters are divided by role; Attackers & Defenders, we’ve included the top 5 R6 Operators for each role. You’ll need to alternate between Attacking and Defending, so it’s a good idea to have a few options for each role:

5 Best Defender Operators in R6 

#5. Mute

A counter-intel and anti-hard breacher specialist, Mute excels at countering the most powerful Attacking Operators in the game like Deimos and Dokkaebi.

With the Signal Disruptor ability, Mute keeps Attackers in the dark without giving the enemies any intel on the objective or your team’s positions by disabling electronic devices.

Paired with shotgun and SMG weapon slots, he’s got everything he needs to handle short & medium-range encounters while stopping hard breaches and drones alike. Plus, he can also bring along a Nitro Cell for destruction at your fingertips!

#4. Mira

While Mira ranges in the harder difficulty to master, she’s a powerful Support Operator with an excellent ability, the Black Mirror. Mira’s Black Mirror lets you place a one-way window on almost any wall to view through it.

If you spot an enemy, break the gas canister to eject the bulletproof glass and shoot through it. She also comes with the Vector .45 sub-machine gun which is a bit difficult to handle, but if you can get used to the recoil, it’s a deadly loadout especially paired with a capable shotty.

#3. Clash

While Clash wasn’t the most prestigious pick, in recent times, she’s having a resurgence especially after some extensive reworks to her kit to greatly improve mobility. What makes her so popular (and deadly) is her Shield, the CCE Shield MK2.

Not only does it protect her fully from incoming fire from the front, but it’s also equipped with a built-in taser that slows and damages enemies in front of her for effective crowd control and denying Attacker rushes.

You can also deploy the shield on its own and take out your firearm to shoot down enemy Attackers and hold power positions. We prefer pairing here with an SMG but the Shotgun works well in short-range encounters as well.

#2. Goyo

To close out pathways and deny areas, Goyo is an incredible Operator specifically built to trap enemy Attackers. With his Volcán Cannister ability, he can place up to 4 exploding canisters that burn the surrounding area in a carpet of fire.

These flames can last a long time, reaching up to 2 minutes, so it’s an effective way to route Attackers to choke points.

And for anyone who gets too close, the Vector .45 SMG and TCSG12 shotgun makes quick work of anyone who gets through, while the Impact Grenade improves his versatility as a Defender.

#1. Azami

Ranking in 1st place, as one of the best Siege Operators for Defenders, is none other than Azami. Azami is a super clutch Defender who can turn the tide of a game by denying enemy breaches by using her Kiba Barrier ability.

Simply throw out kunai to stick to a wall, and the Kiba Barrier will set up and patch any holes in your defense. Paired with her deadly loadout of a 9×19VSN sub-machine gun or ACS12 shotgun, she’s a fantastic pick to deny any area from rushing Attackers.

Plus, she’s literally the closest thing to a ninja we have in Rainbow Six Siege which just gets her some added style points.

5 Best Attacker Operators in R6 

#5. Blackbeard

Blackbeard has seen some nerfs in recent times, but it still hasn’t been substantial enough to get him out of the running as one of the best Attackers in the game. What makes him so OP is his ability, the H.U.L.L Adaptable Shield.

Not only can he use the shield to block incoming fire, but he can also use it to knock down soft walls and enemies. Another unique thing about Blackbeard’s shield is that he can hold it up and use his primary weapon simultaneously.

The ADS is pretty slow, but since his weapons include the powerful MK17 assault rifle, he’s a formidable breach and front-line Operator.

#4. Ash

If you prefer a more ‘simple’ playstyle that’s aggressive and all about flanking enemy combatants, Ash is a top choice. She’s super quick on her feet with a 3-speed rating which makes her great for conquering areas early on.

Plus, she’s got some of the best weapons in the game, the R4-C and G36C assault rifles, both of which have low recoil and uncompromising DPS. Not to mention her ability, Breaching Rounds lets her take charge of soft-breaching to flank enemy operators swiftly while keeping them distracted.

#3. Deimos

If your playstyle revolves around being the clutch player in your squad, Deimos is 1v1-me-bro personified. With his ability, Deathmark Tracker, he sends out a mini-drone probe to sus out an enemy target, revealing their and his location.

During this ‘tracking’, he can only use his .44 Vendetta revolver which packs a punch and simply makes him a menace on any map. Plus, his Primary weapons let him use the AK-74M or a M590A1 shotgun, perfect for pinning down enemies in a firefight.

Deimos excels the lower amount of enemies there are in a round, which has the unintended consequence of being less effective in the early phases.

#2. Dokkaebi

If you prefer to focus more on reconnaissance and gaining intel on your enemies, Dokkaebi is one of the simplest and most effective Operators to do it.

With her ‘Logic Bomb’ ability, allows her to send a virus that rings the Defender’s phones for 12 seconds to sus out their location.

When a Defender is unfortunately killed, she can also take over their phones to access and view a live feed from the Defending team’s cameras. She’s an expert at locating and keeping your team well informed of enemy positions and the best part is she’s pretty easy to play!

#1. Ace

And finally, ranking as the best Attacker Operator in Siege is none other than Ace. Ace is a hard-breacher specialist thanks to his ability, the S.E.L.M.A Aqua Breachers which explodes once if thrown on a floor, hatch, or ceiling, and up to two times on a wall to create a perfect rectangle breach to climb through.

This works on any breachable surface, and with an added bonus that it also destroys Defender gadgets in the vicinity to lower enemy defenses.

Paired with his trusty AK-12 and M1014 shotgun, he’s an extremely versatile hard-breach Operator who made ‘hard-breaching’ great again.

And with that, we’ve reached the end of our list of the best R6 Operators and hope you’ve found a suitable option to main. But the good (or bad) news is, while these characters excel, there are plenty of other Operators that might suit you better.

It’s a matter of pinning down your preferred weapons, playstyles, and gadgets, in which case, they might be a better pick for you than any of the Operators we’ve featured today!
