Aquatic Assault Stormtrooper

Aquatic Assault Stormtroopers, better known as Seatroopers, are a specialized branch of the Imperial Stormtrooper Corps used by the Galactic Empire to maintain a presence on the many aquatic worlds under its rule.

The armor of the Seatrooper is based on the lightweight Scout Trooper design. It is worn over a two-piece environmental body glove that provides protection from uncomfortable temperature extremes or toxic-water environments. The armor is pressure-sealed to a maximum of ten atmospheres and includes a rebreather that allows Seatroopers to stay underwater for more than a hour.

The armor is more flexible than standard Stormtrooper designs, preserving and even increasing a trooper's underwater dexterity. Supplementing the soldier's swimming skills are a back-mounted propulsion unit and a pair of propulsion boots with snap-down flippers. Since blaster ranges are often adversely affected by underwater use, the Seatroopers carry a blaster rifle/speargun hybrid as a standard weapon. The standard Seatrooper utility belt includes high-tension wire, grappling hooks, spare blaster power packs, ion flares, concentrated rations, spare comlink, medpacs, rebreather filters, and a compressed air inflatable bubble tent.
