With the release of Osa in Y6S3, Operation Crystal Guard, Rainbow Six Siege’s operator pool has grown once again. We’ve put together a tier list of the best Attackers and Defenders that you can currently choose from. 

With now over 60 operators to choose from, it can be quite hard to keep up with what’s the current best operator to choose ahead of Year 6 Season 4.

To help you with your struggles, we’ve put together a list of the best Attackers and Defenders, including the newest incredibly versatile operator to hit the game, Osa.

Released with Operation Crystal Guard, Osa is an expert in electromechanics, military engineering, and robotics who was recruited into Nighthaven right after she finished university. This tier list should give you an understanding of where she fits into the current meta.

Osa’s talents and skills make her a formidable attacking Operator.
