Delta Force x Rainbow Six Siege leak Overview
The image is labeled "Information confirmed, deployment in progress," with a mysterious message about to be revealed. As usual, the devs are speaking in riddles and probably think they are being extra witty, but honestly it is pretty obvious. They even pulled out R6's iconic recon drone, so they might as well just reveal it directly! This Delta Force x Rainbow Six Siege leak highlight further strengthens the crossover theme in this section.
In addition, the user "Account Deleted" also posted a recent leak, saying that "the Rainbow Six squad will carry out a joint operation with another unit, and Doc, Vigil, and Montagne are the operators involved in this collaboration." So at this point, the crossover is basically confirmed, especially since this insider has never missed before! This Delta Force x Rainbow Six Siege leak detail also shows how operator identity is carried into Delta Force.
Collab Gold Skin - Doc x Stinger
Quick take: Players familiar with R6 should know that Doc is the medic operator, and his signature gadget is the stim pistol. His role lines up almost perfectly with Stinger in Delta Force.
That said, their character images are still pretty different, and our Delta Force Haji Bee still looks cooler. Hopefully this collab skin turns out great and does not let the rat squad down. This Delta Force x Rainbow Six Siege leak note reinforces the one-to-one character fantasy between both games.
Collab Red Skin - Vigil x Nox
Quick take: Vigil's role in R6 is very similar to Nox's in Delta Force. Both are assassin-type operators. His ultimate can erase his own image from cameras and drones, and when Nox pops the ultimate, Nox can also mask footsteps and block all enemy scan-type abilities. 
Appearance-wise, both operators are masked, but Vigil clearly brings even more pressure. Nox mains are eating good!
Collab Red Skin - Montagne x Sineva
Quick take: This feels great, the most character-accurate pairing of the bunch. Whether it is appearance or abilities, Montagne fits Instructor Sineva perfectly. Sineva's equipment identity is very clear, so once this is made into a red-tier skin, the effects should be very easy to make look great.
The test server just buffed Sineva's handling too, with faster shield-to-gun swapping. Even new Sineva players can get started smoothly now. Add this red-tier collab skin on top, and the Instructor's popularity is definitely hitting a new high!
Delta Force x Rainbow Six Siege leak: Free Pulls Giveaway prediction
Based on past Arknights collab experience, the devs will most likely give out a certain amount of free pulls as shown in the image above.Based on the last collab, they’ll probably give out 79 research tickets, which let you pull 7 times on the same banner — not enough for pity.
Conclusion
Alright, that is everything on the Delta Force x Rainbow Six Siegecrossover! From the stealthy assassin vibes of Vigil and Nox to the tank-like synergy of Montagne and Sineva, the crossover feels both respectful to R6's legacy and fresh for Delta Force players. With Sineva recently buffed and a red-tier skin on the way, the instructor's popularity is set to soar.
