Sandtroopers are specially trained troops of the Empire wich can withstand extreme hot climate conditions such as the deserts of Tatooine. They have a cooling system in the helmets and suit, re-breather on the back with air-filters and water supplies and a long range comlink. The shoulder pauldrons represent the rank of a trooper.
Role in Lego Star Wars
The original sandtrooper minifigure was released in 2004 with the 4501 Mos Eisley Cantina set. It featured the helmet, head, torso, arms and legs of a normal stormtrooper. It also featured an orange shoulder pauldron and a backpack. This figure included a long staff. The set also included a Dewback for the sandtrooper to ride on.
A slightly different variation of the first version of the sandtrooper was later re-released with the 7659 Imperial Landing Craft. This set was released in 2007 and included two sandtroopers. This version featured a black head instead of the original's yellow one and didn't include the backpack.
In 2010, a new version of the sandtrooper was released. It was included with the 8092 Luke's Landspeeder Lego Star Wars set. This version featured a completely new stormtrooper, as well as a redesigned backpack and a black shoulder pauldron.
