I was able to identify the problem last night, It's only with the new "dead space" Skin, if you use any other skin other than this one you normally need 2 AA or Stinger missiles. With the new Skin you are eliminated with just one missile, apparently Dice was unable to fix the problem with this skin 100% .
I was testing last night with a colleague on a private server and I can assure you that this is the problem, however we only tested on the PC version, unfortunately I can't say if the consoles are also having the same problem.
At first I even thought it was some secret Nerf, but things like that would have too big an impact on the game to be hidden from the community. That's why I decided to investigate the situation 🫡
