HPIS-Battle Droid

The HPIS-Battle Droid (Holographic Projection Impersonation System) was an experimental Battle Droid built by Baktoid Combat Automata in a secret factory on one of the moons of Mygeeto. The droids were infamous for their ability to make themselves look almost exactly like someone else. The HPIS-Battle Droids would do so, by taking a snapshot of the person with a built in camera, than project the image from several different holoprojectors, positioned around their bodies.

History
Around 20 BBY, General Grievous, on orders from Count Dooku, placed an order for about one-thousand of Baktoid Combat Automata's new HPIS-Battle Droids, to counter the threats of the Galactic Republic's Clone Commandos. Grievous and the CIS's goal was to confuse the clone commandos into revealing valuable information. Grievous offered a great amount of pay to Baktoid if they completed the job and met his expectations.

Baktoid accepted, and immediately opened up an abandoned factory on one of the moons of Mygeeto to begin construction on the droids in secret. Although the Republic eventually discovered the factory, they never found out what exactly Baktoid was building. In response, the Republic sent Delta Squad, as well as two other clone commando squads, to investigate. While Delta Squad was securing the hangar in which the commandos had landed, the units that had been completed, discovered the two other the squads and killed all of the members. Analyzing the commando's armor, and stealign their weapons, the droids escaped and began to stalk Delta Squad, disquised as the other commandos.
