Zombie bio-operator/doc

Very bad for your health. Avoid.

To add a bit more detail: the bio_op_takedown is a leg kick followed by a CQC slam. Unless you dodge, have some mutant ability that prevents knockdown, or are trained to counter these sorts of things, you're likely to take a significant hit to your torso or head, and be knocked down for a few turns (during which time the bionic operator will continue to attack you). Being a bionic-equipped zombie, they have the Zapback special defense, so consider ranged attacks or wooden melee weapons. These combine to make them an extremely lethal zed for early and middle-game characters, and they remain a credible threat to late-game folks.

However, bionic operators wear & carry milspec gear, and can be dissected for military-grade bionics, so if you think you're good enough, take your best shot! They generally drop at least two high-tier bionics, so be sure to dissect rather than butcher the corpse.

Also, normal zombies when burned to death change into different zombies, which could be an easy way to reduce the risk. The bio-operator is not one of those zombies.
