How Frost in Rainbow Six Siege Controls the Battlefield

Tina Lin “Frost” Tsang is a Defending Operator in Tom Clancy’s Rainbow Six Siege. Introduced in the Operation Black Ice expansion, she is known for her mechanical traps and tactical precision. Frost’s calm and calculated approach to combat makes her one of the most methodical defenders in the game.

Biography of Frost

Tina Lin Tsang was born and raised in Vancouver, British Columbia. At eighteen, she joined the Royal Canadian Air Force and later attended the Royal Military College of Canada, where she graduated top of her class with a degree in Science and Mechanical Engineering.

After completing officer training, she was stationed at CFB Esquimalt with the Joint Rescue Coordination Centre Victoria. She served in the Search and Rescue team that covered British Columbia and the Yukon Territory. Frost’s skill in survival, engineering, and leadership led to her recruitment into Joint Task Force 2, where she took part in Operation Enduring Freedom. In 2015, she was invited to join Rainbow alongside Sebastien “Buck” Côté.

Frost is an avid hunter and has experience using leg-hold traps to capture animals ranging from raccoons to mountain lions. This experience directly inspired her signature gadget — the Sterling Mk2 LHT, also known as the “Welcome Mat.”

Psychological Profile

Frost is known for her exceptional focus and situational awareness. Her mission planning is detailed, and her teammates value her ability to stay calm under pressure. According to Dr. Harishva “Harry” Pandey, the director of Rainbow, Frost’s energy is intense yet controlled. She approaches every task like a finely tuned athlete, bringing precision to every movement.

Her background in Search and Rescue shaped her patience and problem-solving skills. She prefers preparation over improvisation, taking no shortcuts. Frost’s mechanical engineering expertise allowed her to help design and refine the Welcome Mat, making it both portable and effective.

Dr. Pandey also noted that Frost can be reserved when discussing personal matters. A past hunting accident left her with a sense of regret, but it also strengthened her connection to nature. Her friendship with Sanaa “Nomad” El Maktoub reflects their shared respect for the wild and endurance through adversity.

Frost’s personality combines analytical discipline with a quiet intensity. She is most comfortable in structured environments and thrives when working alongside teammates who respect her methodical nature.

Gameplay Overview

Frost is a medium-health Defender equipped with three mechanical traps called Welcome Mats. These devices incapacitate enemies who step on them, putting them into a down-but-not-out (DBNO) state. Her role revolves around area denial and surprise. By placing traps in key entry points, Frost controls the pace of an enemy push and punishes careless movement.

Loadout

Primary Weapons

• Super 90 Shotgun

• 9mm C1 Submachine Gun

Secondary Weapons

• Mk1 9mm Handgun

• ITA12S Shotgun

Gadgets

• Bulletproof Camera x1

• Deployable Shield x1

Her flexible loadout allows her to adapt to close or mid-range defense. The 9mm C1 offers stability and moderate damage, while the Super 90 is ideal for tight spaces. The ITA12S secondary shotgun provides utility for creating rotations and trap setups.

Frost’s Ability: The Welcome Mat

The Sterling Mk2 LHT “Welcome Mat” is Frost’s unique gadget. It is a floor-mounted, spring-loaded trap designed to immobilize enemies without killing them. The trap is purely mechanical, making it invisible to electronic scanners.

Each Welcome Mat takes about three seconds to deploy and can be placed almost anywhere on the floor. Attackers who step on it are immediately incapacitated and cannot crawl or revive themselves through gadgets like Finka’s Adrenal Surge or Doc’s Stim Pistol. They must be manually revived by a teammate.

If a player who has already been downed once in a round steps into a Welcome Mat, they die instantly. Attackers can destroy a mat by shooting it, though it can absorb significant damage before breaking.

Strategies and Tactics

Frost’s strength lies in her ability to punish predictable movements. Placing traps under windows, near vaults, and behind deployable shields can easily catch attackers off-guard. Combining her traps with environmental distractions or other gadgets enhances their effectiveness.

Best Tactics for Frost:

• Hide Welcome Mats under barbed wire to reduce visibility.

• Pair with Bandit or Kaid, as electrified wire above a mat can quickly eliminate trapped enemies.

• Work with Smoke to trap attackers in toxic gas as they struggle to escape.

• Coordinate with Caveira to interrogate downed enemies for intel.

• Use Oryx’s dash or Thorn’s traps to push or finish off trapped attackers.

Her traps are especially effective when attackers are rushing or vaulting through windows. Players should, however, be cautious of explosives and drones that can destroy or reveal her traps before use.

Counters to Frost

The Welcome Mat is vulnerable to explosives and sustained gunfire. Attackers can clear it safely with frag grenades, impact grenades, or by shooting it before vaulting. Drones can also scout for traps, allowing attackers to avoid them entirely.

Despite these counters, a single misstep can turn a round in Frost’s favor. Her traps excel when the enemy is under time pressure or distraction. Even when destroyed, the threat of their presence slows attackers down, buying valuable seconds for defenders to reposition.

Device Evaluation

Specialist Liu “Lesion” Tze Long, who worked with Frost to test the Welcome Mat, praised its simplicity and reliability. Their evaluations confirmed that while the device is effective on its own, it performs best when paired with other defensive tools like Gu Mines or electrified wire.

The Welcome Mat’s mechanical nature ensures that it cannot be jammed or detected by electronics. This reliability makes Frost a valuable operator in defending objectives where Attackers rely heavily on gadgets or scanning technology.

Trivia and Character Details

 

Frost marks her blood type, B+, on one of her gear pouches, and her default uniform displays the Under Armour logo. Her pocket shows the Chinese character “霜,” meaning “Frost,” as a subtle nod to her codename. She fought in Operation Enduring Freedom with Warden, Alibi, Blackbeard, and Maverick, showing her real combat experience. In in-game voice lines, Frost hints at a romantic relationship with Fenrir. In Rainbow Six Mobile, her gaiter is removed, showing her full face, and she also appears as a playable character in the mobile game Arknights. Her favorite holiday growing up was Halloween, though her mother often warned her that too much candy would give her nightmares. These small details give Frost a more human side, contrasting with her otherwise cold and disciplined persona.

Frost’s Legacy in Rainbow Six Siege

Frost represents the balance between engineering precision and field adaptability. Her design philosophy — efficiency through simplicity — is clear in how her gadget functions. While many operators depend on electronics or advanced technology, Frost’s mechanical traps remind players that straightforward tools can be just as deadly in skilled hands.

Her calm demeanor and disciplined mindset reflect her Search and Rescue roots. Whether securing a room, delaying attackers, or supporting her team’s defensive setup, Frost remains a steady presence. Her ability to turn a misplaced step into victory makes her one of the most iconic defenders in Rainbow Six Siege.
