The Jamil Organ (or Jamil Engine) is an ECM (Electronic Countermeasure) generating biological device that certain beasts possess. They are designed to disable enemy communications, targeting, tracking and other sensitive electronic equipment. It was named after the physicist Jamil, who discovered it.

This technology was first shown in The Arin War, when 32 Guardians used Jamil and Chamild Organs to isolate the planet from outer space.
