The armor permutation glitch is a glitch that can be performed in Halo: Reach and Halo 4. The result of the glitch would create a randomized character model along with armor details. If the Hologram creator uses an Elite model, the hologram will have a white Minor armor and a random Armor Effect. The same applies to the Spartan model, whereby the hologram will get any randomised armor in the game.
This glitch only works while not the connection host.
It is possible to generate armor permutations not actually obtainable in-game. The dead Spartans on Lone Wolf are also capable of being generated with unobtainable armor combinations.
