A creation of the prolific Balmorran Arms corporation, this older model war droid was first conceived and manufactured during the cold war between the Galactic Republic and the Sith Empire in the early fourth millennium BCGT. Like many war droid models of this size, the BAF-1000 is essentially humanoid in form. It is bipedal, with a pair of arms high up on the sides of the torso and a distinct cranial unit atop the main body. The droid possesses a rugged internal skeleton capable of resisting moderate amounts of blaster fire as well as additional durasteel plates that form a cuirass to protect the torso, greaves to protect the lower legs, and vambraces to strengthen the droid's forearms. Angular plates form pauldrons to protect the shoulder joints and encase the head in an armoured, flattened dish-shaped casing.

The droid lacks a discernable face, possessing merely a row of glowing photoreceptors along the front of its head as well as a simple box-like vocabulator. Unlike many larger combat droids, the BAF-1000 does not possess built-in weapons. Its purchasers would equip the droid with domestically produced blaster weapons, which the droids can easily hold and manipulate in their strong four-fingered hands. This gives the BAF-1000 a respectable degree of tactical flexibility, a useful trait in a fighting droid.

Production of this model has long since ceased and the droid has been replaced in most organised forces by newer models such as the BX or B1series. They are hardy droids though, and can still be encountered on rare occasions by the lucky or the unlucky.
