Explosive collar

Explovise collars are a recent device developed by the Terrans used to control zerglings that have been "lobotomized". How the zerglings are "controlled" is unknown. Given that the Zerg lack any self-preservation instincts on an individual basis, the treat of death is unlikely a factor. Each device can be triggered to detonate remotely. Should the remote malfunction, the zerglings would immediately attack the handler.
