Alongside Death Star Troopers, Imperial Officers replaced the customization that allowed for "helmetless stormtroopers."
There is no armored variant for the Imperial Officer regardless of the map that the skin is equipped on.
The sequel game, Star Wars Battlefront II (2017), features armored Imperial Officers on some maps, such as on Tatooine.
Imperial Officers were first seen in A New Hope and reappear in all subsequent films in the original trilogy. Drafted from recruits trained at specialized academies, Imperial Officers are expected to be loyal, highly ambitious, and fully supportive of the Empire's political ideas, such as the subjugation of alien, non-human species.
This xenophobia is realized in-game as well, where only humans head Appearances can be used to customize the Imperial Officer body.
