1. ↑ This is the insignia for a UNSC Master Chief Petty Officer. However, in Halo 3 the insignia for Master Chief Petty Officer of the Navy is shown to be the same as for the US(with the standard "crow" changed for that of the UNSC "crow"). It is inferred that this applies to all UNSC Navy Enlisted rank insignes.
