How This R6 Tier List Works

In our R6 Tier List, we’ll categorize operators into tiers (S, A, B, C, D, E) based on how consistently they perform across maps, game modes, and skill levels in 2025.

1. S-Tier - Top meta picks; strong in almost any situation, an excellent choice in every game.

2. A-Tier - Very strong choices who are reliable, just a few limitations or stronger situational picks.

3. B-Tier - Solid picks that are good in many cases, but have distinct drawbacks or are slightly more niche.

4. C-Tier - Situational yet useful in specific maps, team compositions, or strategies; less reliable in general play.

5. D-Tier - Under-performers or operators with significant handicaps in the current siege meta.

We’ll split the list into Attackers and Defenders, since roles and utility differ significantly. Also, please remember that even a “low” tier operator may be the perfect fit for your style, squad synergy, or map strategy.

R6 Attackers Tier List 2025

The attacker meta favors flexible entries and coordinated breachers. Ace, Thermite, and Iana lead the R6 attackers tier list due to their universal usefulness, while Zofia and Nomad offer map control that wins rounds consistently.

S-Tier Attackers

These Operators dominate across maps and modes thanks to unmatched utility or meta-defining gadgets.

• Ace – Fast, adaptable, and perfectly balanced. His throwable hard-breach charges make wall openings safe and efficient, while his rifle gives him strong dueling power. It’s no wonder he tops almost every ranked lineup.

• Thermite – The classic hard breacher who still defines the role. His exothermic charges remain unmatched for opening reinforced walls, and his gunfights feel clean thanks to steady recoil and damage. One of the best R6 characters - reliable, simple, and always effective.

• Thatcher – The king of utility denial. His EMP grenades continue to disable key defender gadgets with ease, making him the foundation of most coordinated pushes. Even after countless nerfs, teams still build around him.

• Iana – A hybrid of recon and raw aim. Her hologram clone allows safe scouting while she uses top-tier rifles to clean up behind her intel. She fits nearly any strategy, from solo flanks to full executes.

• Zofia – A versatile entry who adapts to almost any situation. Her launcher handles both stuns and explosives, while her strong gun setup keeps her competitive in every gunfight. Few attackers bring this much all-around value.

• Nomad – Roam control at its finest. Her Airjabs shut down flanks, secure post-plants, and protect teammates during rotations. Nomad doesn’t just hold space - she dominates it quietly and efficiently.

Traditionally good picks like Ace and Thermite sit comfortably at the top of the list of best R6 operators in 2025. Their combination of raw utility, team synergy, and strong weapon and attachments options makes them essential in both ranked and pro-level play. Every round feels more controlled and predictable when at least one of these Operators is on your squad.

A-Tier Attackers

Strong, dependable picks with slightly narrower niches when compared to the R6 Siege best attackers of 2025 listed in the S tier.

• Maverick

• Hibana

• Finka

• Zero (Sam Fisher)

• Jackal

• Brava

• Ram

• Sledge

• Ying

• Fuze

• Lion

Attackers such as Maverick, Hibana, and Finka show just how valuable flexibility can be. They may not dominate every matchup, but they perform consistently across most objectives. These picks reward planning and coordination, making them staples in R6 character tier list.

B-Tier Attackers

Balanced and serviceable, though meta shifts or counters hold them back slightly.

• Dokkaebi

• Capitão

• Osa 

• IQ

• Grim

• Sens

• Flores

• Deimos

Operators like Dokkaebi, Flores, and Capitão offer great value when used with precision. They might not be the best operators in Rainbow Six Siege, but their gadgets are still able to punish careless defenders. They’re perfect for players who prefer tactical creativity over raw aggression.

C-Tier Attackers

Viable in casual or specific map strategies, but less consistent overall.

• Blackbeard

• Capitão

• Nøkk

• Gridlock

• Glaz

• Kali

• Finka

Picks such as Gridlock, Nøkk, and Kali can still win rounds but rely on very specific conditions. They’re best suited for maps where flanking, stealth, or long-range control make a difference. In most situations, though, they’ll need strong teammates to cover their weaknesses.

D-Tier Attackers

Limited or outdated; used rarely in the current competitive environment.

• Blitz

• Montagne

• Amaru

Operators like Blitz, Montagne, and Amaru are fun situational picks. Their kits can surprise uncoordinated teams; sometimes, even in high-level ranked play, they’re dark horses.

R6 Defenders Tier List 2025

S-Tier Defenders

These Operators define the current defender meta - they’re perfect for intel denial, utility countering, or site anchoring.

• Jäger – A timeless pick that has proven himself to be one of the best R6 characters. His ADS devices stop grenades, projectiles, and anything else that could break a setup. He’s reliable on every single map.

• Mira – Her Black Mirrors remain one of the most defining gadgets in the game. They reshape sightlines, force attackers to waste utility, and make defending feel entirely different.

• Aruni – Smart, adaptable, and efficient. Her Surya Gates cut off sightlines, slow pushes, and even deny drones. She’s a natural fit in nearly every defensive setup.

• Wamai – A flexible alternative to Jäger who trades coverage for creative placement. His Mag-NETs catch crucial projectiles and let defenders hold positions longer than they should.

• Smoke – His gas grenades win rounds by denying plants and locking down final seconds. A clutch player’s dream operator.

• Azami – Her Kiba Barriers redefine what “map control” means. With smart placement, she can seal off sightlines, block entry points, and create positions attackers simply can’t challenge.

Timeless classics such as Mira, Jäger, and Azami continue to control how rounds are played. Near-perfect kits are what discerns R6 Siege's best defenders in 2025 from their lower-tier counterparts. Their gadgets are excellent at controlling sightlines and granting game-defining utility. If you’re building a team around consistent performance, these are the operators to start with.

A-Tier Defenders

Strong anchors and roamers who complement S-tier operators.

• Bandit

• Kaid

• Mozzie

• Mute

• Valkyrie

• Melusi

• Fenrir

• Lesion

• Tubarão

Operators like Valkyrie and Mute form the backbone of most successful defenses. Their balance of intel, utility denial, and adaptability makes them reliable across all maps. Even without flashy abilities, their presence keeps attackers guessing.

B-Tier Defenders

Solid options that shine on certain maps or with specific team roles.

• Castle

• Kapkan

• Maestro

• Alibi

• Ela 

• Thorn

• Warden

• Pulse

• Doc

• Rook

Defenders such as Alibi, Kapkan, and Maestro excel when used with intent and map knowledge. They might not fall into the best siege characters category, but when played by confident players, they deliver real results. These are the kind of picks that reward deep familiarity with site layouts.

C-Tier Defenders

Playable but not preferred in serious ranked or pro setups.

• Goyo

• Oryx

• Caveira

• Frost

• Thunderbird

• Clash

• Tachanka 

Operators like Frost, Oryx, and Goyo still have niche value for creative setups. Their utility can delay attackers or create unexpected pressure, but they lack the consistency of higher-tier siege meta picks. They’re great for players who enjoy off-meta defensive strategies.

D-Tier Defenders

Rarely seen and struggling to provide consistent value in ranked play.

• Solis

• Vigil

• Skopos

Picks such as Solis, Vigil, and Rook fall short in the fast-paced 2025 meta. Their tools just don’t match the impact of stronger utility options, leaving them rarely chosen in serious play. They’re best left for casual rounds or experimental strategies.

Summary Table

With our tier list coming to an end, let’s summarize everything with the handy cheat sheet:

With this info at hand, you are set for success in every tier of ranked play. Don’t forget that lower-tier characters are still capable of providing a lot of value and hold some degree of surprise factor. 

Conclusion

This tier list is designed to give you a current snapshot of how operators stack up in 2025 for Rainbow Six Siege. We’ve got Rainbow Six Siege operators ranked based on their utility, flexibility, and meta relevance. However, of course, your personal proficiency and teamwork matter far more than a letter grade.

If you see an operator you like in B or C tier, that doesn’t mean they’re implicitly bad. It just means they’re less guaranteed to perform well compared to S/A tier picks under a wider range of circumstances. Use this list as a starting point, pick what suits your playstyle, and lean into roles that match your strengths (whether that’s entry-fragging, intel gathering, roaming or support).
