Dalek Lieutenant
From Tardis Wiki, the free Doctor Who reference
As observed by Landinalakallinian, Dalek Lieutenants commanded Dalek companies, with two equal-sized companies forming a battalion commanded by a Dalek Captain. Dalek Lieutenants and Captains did not seem to be distinguishable from exterior appearance, with the Gallifreyan professor suggesting that they relied on forms of radio identification signals to identify each other instead of more obvious rank markings.
