My COBRA zombies are based on the infected from Left4Dead, and were a fun way to use up some fodder. Most of these parts were ones I had laying around, I tried to only use existing fodder for my zombies without having to obtain new parts. They're quick and dirty but I'm pretty happy with how they came out, especially as a set.
While I wanted these zombies to be recognizable as infected COBRA troopers, I also decided to omit the COBRA symbol so they could be used as more generic zombies with a headswap if I ever had the need. The Hunter's uniform has blood over his symbols, while the Smoker's uniform has been torn in the spots the Cobra emblem usually appears.
