Here’s another Star Wars helmet inline with all my other helmets mocs
It’s the Death Star Imperial Gunner helmet.

Imperial gunners/engineers were members of the Imperial Navy’s Starfighter Corps (acting as a special sub-unit of the corps) who manned the various weapons and engine rooms of the Empire’s capital ships, military bases, and both Death Stars.The most advanced were involved in the firing and maintainence of the reactors within the first and second Death Star.
