ZQ Infantry Droid
developed by Sienar Intelligence Systems, this droid was created to serve as infantry support during ground battles. In this capacity, the ZQ was well-designed, and was considered one of the most deadly battle droids ever produced. Measuring about a meter in height, this cylindrical ZQ moved about on a repulsorlift engine and was armed with a heavy blaster cannon, a light blaster cannon, and a miniature concussion missile launcher. After the Battle of Endor, the Empire denied having any ZQs in active duty, despite their presence on many battlefields.
