FBI

Lore & Background

The FBI's place in the Rainbow Six Siege narrative is rooted in the agency's long-standing mandate to counter domestic and international terrorism on American soil. When the escalating wave of coordinated attacks—driven by a shadowy, ideologically fractured terrorist network—made it clear that no single national agency could respond alone, the FBI placed its most decorated tactical operators into the multinational pool. Their selection was not merely about firepower; the coalition valued the FBI's forensic tradecraft, its intelligence-sharing infrastructure, and its willingness to operate under allied command structures without surrendering operational integrity.

Within the game's tactical framework, FBI operators are characterized by a philosophy of controlled escalation. Smoke's chemical denial zones and Thatcher's electromagnetic pulse rounds both serve a common doctrine: shape the battlefield before the enemy can shape it. This mirrors the real agency's emphasis on preparation, intelligence-driven targeting, and minimizing civilian casualties through precision rather than brute force. In the broader Siege storyline, FBI personnel frequently find themselves at the intersection of domestic jurisdiction and international cooperation—a tension that the game portrays through the operators' loyalty to both their national duty and the shared mission.

The FBI's contribution also carries a quieter narrative weight. Where some task forces are defined by their combat prowess, the FBI's operators in Siege often embody the investigative and protective side of counter-terrorism: securing perimeters, disabling the enemy's technological edge, and buying time for the coalition to close in. This makes them a stabilizing presence in the roster, a reminder that the coalition's strength lies as much in coordination and preparation as in the final breach.

In Their Own Story

The fluorescent hum of the safehouse in downtown Manhattan was the only sound for eleven minutes. Smoke crouched behind a overturned sedan, watching the thermal bloom of two hostiles peel away from the alley mouth. He exhaled slowly, the taste of cordite still on his tongue, and keyed his comm. "Thatcher, you're clear on the east face. I need ninety seconds."

A pause. Then the dry click of a round chambering. "Ninety's generous, partner. I'll give you sixty."

He pulled the pin on the second canister, felt the familiar weight settle into his palm. Outside, the November rain had stopped, leaving the streets slick and black, reflecting the amber glow of a single streetlamp. Somewhere three blocks south, a generator whined to life—Thatcher's EMP round, cooking the enemy's comms and optics into useless glass. Smoke grinned behind his mask. The room was his to own now. He rolled the canister forward, watched the white cloud swallow the doorway, and stepped in.

Reader's Guide

The Federal Bureau of Investigation (FBI) is a United States federal law-enforcement and counterintelligence agency whose mandate encompasses investigating federal crimes, conducting counter-terrorism operations, and protecting the nation from domestic and foreign threats.

In Rainbow Six Siege, the FBI contributes two operators to the Rainbow coalition. Smoke (Wesley Smith) serves as a Defender whose chemical gas grenades create persistent denial zones that block enemy sightlines and slow their advance, embodying the agency's protective and perimeter-security doctrine. Thatcher (John Harris) is an Attacker whose EMP grenades disable electronic devices—including enemy gadgets and reinforced walls—reflecting the FBI's emphasis on neutralizing technological advantages before a breach. In-universe, both are drawn from the FBI's elite tactical and investigative units, and their kits complement each other: Thatcher strips the enemy's electronic edge while Smoke locks down the space they're trying to hold. The game presents them as a natural pairing, though they operate independently on the field, each answering to the broader coalition command structure rather than a single national chain.

• Smoke's gas grenades in Rainbow Six Siege create a persistent cloud that blocks line-of-sight for both attackers and defenders, making him one of the few operators whose ability affects both sides of the round.
• Thatcher is one of the few attackers in the game whose gadget can disable enemy-placed gadgets in addition to breaching reinforced walls, giving him a unique anti-gadget role on the attacking team.
• The FBI is one of several national agencies represented in the Rainbow Six Siege roster, which also includes units from the UK, France, Spain, Germany, and numerous other countries, reflecting the game's multinational co
• Both FBI operators in the game are designed around a 'shape the battlefield' philosophy rather than pure firepower, mirroring the real agency's emphasis on preparation, intelligence, and precision over overwhelming force
