Badass Scavs are the Badass version of Scav enemies. They have increased health and damage output, and can fly around on jetpacks. They have an enclosed metal faceplate acting as a helmet, which cannot be shattered, unlike regular Scav units.
As with other Badass units, these enemies will be more difficult to take down than their non-Badass versions. Badass Scavs have what appears to be a shoulder-mounted rocket launcher, but in Normal mode these appear to be decorative only.
