Two new Operators have been added with the Operation Dust Line update for Rainbow Six: Siege: Valkyrie and Blackbeard, both from the US Navy Seals.
Valkyrie is a defensive operator and carries four cameras that can be thrown and accessed by anyone on the team. They can be picked up again if thrown in the wrong spot, and while are small do give off a blue light alerting enemies to their position.
Blackbeard is an attacker with a transparent shield attached to his weapon. It can be shattered after taking a lot of hits, and it still leaves you vulnerable to shots from the side and back.
These two new operators are available to season pass holders already, though other players will have to earn points through gameplay to unlock them for play. You can check out both operators in action below:
