Combat Implant
developed during the decades leading up to the Great Sith War, a combat implant was essentially a small computer system was implanted into a being's body. The computer was linked to the user's brain, and provided a constant stream of data about battle situations. It could provide weapons specifications, troop estimates, and other tactical information at the user's request, allowing them to make swift, informed decisions as a battle raged around them. The technology behind the combat implant was experimental at best and prohibitively expensive, and never saw widespread usage.
