Sébastien "Buck" Côté

Sébastien "Buck" Côté is an Attacking Operator featured in Tom Clancy's Rainbow Six Siege, introduced in the Operation Black Ice DLC expansion alongside Frost. He has medium armour and mobility, and is equipped with an under-barrel mounted shotgun known as the "Skeleton Key", useful for creating breaches with ease.

A Montreal native, Côté was born on 20 August 1980 and always wanted to lead an unconventional life. He enrolled in the Canadian Armed Forces via the Regular Officer Training Plan, which allowed him to attend University and obtain a degree in Criminology. After graduation he became an MP in the Canadian Army. When his time in the Army was completed he joined the Royal Canadian Mounted Police and eventually became a part of the Emergency Response Team. After excelling in his ERT role he was invited by the Canadian military to re-up and become a member of JTF2.

Highly pragmatic, Côté will always take the shortest distance between two points. He is not one to mince words or become hyperbolic. He enjoys simple mechanical devices rather than the more high-tech arsenal employed by other members of Team Rainbow.
