Energy garrote

The Energy Garrote is a small two-piece cylinder that splits apart in the middle causing a green arc to form between the pieces. This weapon is commonly used to choke and burn an enemy quietly from behind. It is used mostly by Special Ops Elites.

The Energy Garrote is not seen in any of the Halo games in the series, but is used in Halo: The Flood by Zuka 'Zamamee to kill Rick Hale, the pilot of a Pelican, and take control of the craft to land at the human Alpha Base on Installation 04. It is so theorized that the Energy Garrote is factually a simple energized wire used to strangle the enemy by a silent choking death, similar to the modern day fiber-wire.
