A3AA personal defense module

From Wookieepedia, the Star Wars wiki.

"The biggest problem with the A3AA is its lack of physical protection. Sure, it'll dispel a blaster shot just fine, but as soon as I realize I'm up against someone with this kind or [sic] armor, I start firing a slugthrower or lobbing grenades."

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.
