Rebel soldiers employ a shield generator, protecting themselves against AT-ST weaponry.
A shield projector, also referred to as a deflector shield generator, shield generator or shield array, was a piece of equipment designed to produce a deflector shield, for instance, a ray shield.
The Galactic Empire positioned a SLD-26 planetary shield generator upon the forest moon known as Endor. The shield delivered safeguarding for the Empire's formidable DS-2 Death Star II Mobile Battle Station superweapon; its activation ensured the weapon could not be harmed by the attacks carried out by the Rebel Alliance forces.
During the Clone Wars era, the military forces within the Unknown Regions utilized electrostatic barriers which shared a similar purpose to the deflector shield generators that were commonplace in most of the galaxy, though they offered significantly less power. This prompted Thrawn to retrieve a deflector shield generator, which he called a "Republic energy shield," from the Separatist droid factory located on Mokivj and return it to his people after aiding Jedi Knight Anakin Skywalker during his mission to Batuu. Thrawn would subsequently use the "Republic energy shield" in the Battle over Primea to assist in the defeat of Nikardun general Yiv the Benevolent, thereby bringing an end to the Nikardun conquests.
