In the Star Trek: Prometheus continuity, in 2379 Starfleet Command made a change to the enlisted officer collar rank insignia changing the pips to a silver rectangle like the style of pip that was used by United Earth Starfleet when the Enterprise NX-01 was launched. Cadet pips were changed to a silver rectangle with black bars to indicate which year the cadet was. Warrant officer pips were changed to a silver version of previous design.
