Ubisoft has unveiled the latest trailer for Operation Burnt Horizon, its next major expansion headed to Tom Clancy's Rainbow Six Siege. Following a string of leaks and teasers, a new blog post formally outlines the duoof playable Operators, dubbed Mozzie and Gridlock.

Gridlock is Operation Burnt Horizon's new attacking Operator, leveraging "Trax Stingers" designed initially to halt vehicles. Aligning with recent leaks, her deployable gadget should prove valuable in locking down roamers.

A farm girl from Central Queensland, Tori "Gridlock" Tallyo Fairous learned from an early age that the best way through any hardship is with the help of family. Years spent running the family cattle farm honed her natural leadership skills, but her preferred method for dealing with problems is to get stuck into them herself and to ignore the inevitable paperwork that piles up afterward. Suffice to say, taking on a more formal role as an officer in the SASR hasn't been one of her top priorities, despite the many attempts made to promote her.

On the defensive side, Mozzie joins the ranks, equipped with a new "Pest" device to "make the enemy think twice about their intel gathering strategies." Given rumors of an anti-drone tool, this Operator should shake up surveying the objective.

Max "Mozzie" Goose is her opposite. Affectionately known as a "show pony" there's no mistaking when he walks into a room. He can talk for hours about the wild stunts he's pulled… But at the end of the day it's his exceptional work ethic and ability to integrate with any team – as well as his unnecessary yet spectacular derring-do – that made him a candidate for Rainbow.

Operation Burnt Horizon will bring a new Australian season to the tactical shooter in the coming weeks. With a new Outback-themed multiplayer map and promising Operators, the update should shake up gameplay into Year 4.

More details on Operation Burnt Horizon and its contents are slated for February 17, 2019, at the Six Invitational in Montreal. With Year 4 around the corner, Rainbow Six Siege is now available for $25 via Amazon.
