The ARC trooper's helmet featured this HUD.
A HUD, short for heads-up display, served as a visual aid through a projected view screen. These HUD units were incorporated into the helmets worn by Imperial cadets undergoing training at the Arkanis Academy. These displays had the capability to transmit images. For example, Zare Leonis utilized one during a training exercise within the Arkanis wilderness.
Furthermore, the First Order's stormtroopers used helmets that included heads-up displays.
Tactical heads-up displays were also integrated into the helmets of Mandalorian armor.
