Type-27 Responsive Holographic Form Emulator

The T-27 Responsive Holographic Form Emulator, also known as Holographic Decoy or Hologram is an armor ability featured in Halo: Reach and Halo 4. This responsive emulator generates an extremely realistic holographic copy of the user's physical form and movement and was once used exclusively by the Covenant. However, this decoy technology has now been reverse engineered for MJOLNIR armor systems, and is used as a ruse in the field to trick enemy infantry and armor into revealing their position, thereby placing them at a disadvantage.
