Seatrooper

Seatroopers were a specialized variant of stormtrooper in the Galactic Empire's Stormtrooper Corps trained and equipped for aquatic operations. Unlike standard stormtroopers, seatroopers used breathing apparatuses, scuba backpacks, underwater propulsion jets, and fins that allowed them to operate in aquatic environments. They were deployed during Imperial operations on Mon Cala and were also used in training exercises for Imperial cadets on Carida and Lothal. Stormtroopers equipped with underwater armor were later used on Madurs shortly after the Battle of Endor.
