A3AA personal defense module
From Wookieepedia, the Star Wars wiki.
The A3AA Personal Defense Module was a set of armor manufactured by Corellian Technologies. While it offered only limited physical protection, it provided effective protection against blaster bolts by emitting a dissipation field. This was created by spraying a mixture of refined courenth with trace amounts of ves added. The design was mostly used by Imperial scouts, having been based on a idea originally conceived by Rebel Alliance tactican, General Airen Cracken. The suit had two main modes: a five-meter-diameter cloud, or a forward facing cone covering 30 degrees.
