Just so you're aware, The Man on Fire was most certainly a zombie, and based on what Code Talker and Skull Face said, those two were zombies as well (well, technically, they're closer to liches than Zombies since they actually retained their wills rather than losing them, but still...).

Also, it's a common misconception that zombies refer exclusively to undead people. There are also zombies that are actually alive, and in fact, the original meaning of zombies were people who were brainwashed into slave labor. Para-Medic explains this in Portable Ops via a radio conversation.
