- "Junior officers don't get to tell senior officers how to do their job."
- ―Ensign Eli Vanto
Junior officers formed the lowest operational commissioned officer category of military ranks, ranking below senior officers in the Starfleet of the Galactic Empire. Those junior officers were ensigns, junior lieutenants, and senior lieutenants.
The various First Order personnel aboard the Mega-class Star Dreadnought Supremacy were technically closer to this rank, although they held ranks much higher than that such as lieutenant and gunnery chief. This was because various members of the First Order's military forces were trained for direct combat since birth.
