Tom Clancy's Rainbow Six Siege has evolved dramatically, with the roster of attackers expanding from its original 10 to a formidable 38 in the current Siege X landscape. In this high-stakes competitive shooter, attackers are tasked with breaching defenses, gathering intelligence, clearing enemy gadgets, and aggressively eliminating defenders to secure victory. While nearly all operators are viable, some consistently outperform others in the ever-shifting meta of 2025. Choosing the right attacker can be the difference between a flawless victory and a crushing defeat.
10. Finka: The Universal Support
Finka's unique global ability to heal, buff, and even revive her entire team with a press of a button remains a game-changer. While support is often associated with defenders, Finka's consistent high win delta proves the immense value of on-demand healing in a game with no respawns. Her kit, featuring an LMG and grenades, combined with the self-buffs from her own ability, makes her fantastic for playing as an aggressive entry fragger. However, she can also anchor a supportive role, ensuring her team stays in the fight from anywhere on the map.
9. Twitch: The Gadget Hunter
Intel denial is a cornerstone of a successful attack, and Twitch reigns supreme in this domain. Twitch’s drones outright destroy electronic gadgets and can be driven around to all parts of the map safely, clearing traps, jammers, and cameras with precision. The primary risk is her drones becoming priority targets for vigilant defenders. Armed with the high-reward, high-skill F2 assault rifle or the reliable 417 marksman rifle, a skilled Twitch player can clear the path and frag out.
8. Deimos: The Roamer's Bane
Deimos's design forces a high-risk, high-reward duel, but his true strength lies in coordinated play. While his gadget reveals his location to the target, if you’re playing with a well-coordinated team, you can simply tell them where the enemy is. This makes life miserable for roamers, who are forced to retreat or face a pre-aimed team. His loadout, including the M590A1 shotgun for soft destruction, supports a versatile playstyle focused on flushing out hidden defenders.
7. Blitz: The Lightning Bruiser
In a game defined by angles and peekers' advantage, Blitz offers a terrifying alternative. Blitz is a shield operator whose goal is to move fast and hit enemies like a freight train. His flash shield allows him to close distance while blinding opponents, creating panic and opening opportunities for easy kills. While he can be a distracting support, he excels at isolating and eliminating defenders caught off guard.
6. Maverick: The Uncounterable Breacher
Hard breaching is pivotal, but most operators who do it have clear counters like Bandit or Kaid. Maverick, however, has no real counters for some reason. His quiet blowtorch can silently carve holes in reinforced walls, create murder holes, or even destroy defender gadgets on the other side. This makes him an invaluable, flexible pick. As a three-speed operator with the excellent M4, he can also serve as a potent entry fragger, fitting seamlessly into any team composition.
5. Dokkaebi: The Information Warfare Specialist
Dokkaebi excels at dismantling the defender's information game. Her Logic Bomb forces all defenders' phones to vibrate loudly, revealing the positions of lurking roamers. Once that first roamer is taken out, she can hack their cell phone and get access to the entire camera network of defenders, flipping the intel war on its head. While she lacks an automatic primary, her three-speed rating and supportive gadget make her a nightmare for defensive setups.
4. Ash: The Quintessential Entry Fragger
A perennial favorite, Ash embodies speed and aggression. As a three-speed operator with the potent R4-C assault rifle, she’s perfect for running in and killing defenders before they have time to react. Her breaching rounds offer utility for destroying gadgets or opening quick sightlines, but her primary role is straightforward: enter the site first and frag out. This makes her exceptionally strong in fast-paced modes like Dual Front.
3. Buck: The Vertical Master
Buck's strength lies in controlling the map's verticality. His underbarrel shotgun, the Skeleton Key, allows him to quickly open floors and ceilings, attacking defenders from completely unexpected angles. This soft-breaching power lets him apply immense pressure away from fortified doorways. With a strong primary weapon in the C8-SFW and stun grenades, he can transition from creating angles to capitalizing on them as a lethal entry fragger.
2. Ace: The Versatile Hard Breach King
For reliable, safe, and effective hard breaches, Ace is the top choice. He can deploy his gadget from a short range, making him much safer to use than Thermite. His Selma charges also deploy faster initially, making them harder to trick or destroy. While it takes two charges to open a reinforced hatch, this is a minor trade-off for his overall package, which includes the devastatingly strong and easy-to-control AK-12 assault rifle, cementing his status as a must-pick for new and veteran players alike.
1. Blackbeard: The Redeemed Phantom
After years in the wilderness, Blackbeard's 2025 rework has returned him to a position of formidable power. Unlike other shield operators, he isn’t holding a pistol at his side, but his iconic Mk17 CQB (or the SR-25 marksman rifle). His unique shield allows him to hold angles with an assault rifle while protected from headshots. The ability to breach soft walls with his shield and throw grenades without lowering it adds unprecedented utility. While he must lower the shield to fire, the protection it offers during peeks makes him a uniquely oppressive force, finally reclaiming a spot at the top of the attacker meta.
