The Armor Permutation Glitch is a Hologram that can be performed in Halo: Reach and Halo 4. The bug creates a Hologram without a source player model to copy from. When an Elite player performs the glitch, this can result in an Elite Hologram with white Minor armor and a random Armor effect, or in an Elite Hologram with all customizable armor pieces missing. When a Spartan player performs the glitch, a Hologram with completely random armor results, which do not synchronize (all players in the game will see different armor).
