the B1 battle droids were battle droids that made up the backbone of the Trade Federation Droid Army and the Separatist Droid Army. It was the successor of the hunter-killer droid.

B1s were perhaps the most numerous—and expendable—soldiers in galactic history, and, unlike most organic soldiers, they were capable of action in hostile environments like underwater or in space. They were designed, for the most part, to defeat their enemies through sheer numbers, not through their ability to think and utilize combat skills (unlike clone troopers).

B1 battle droids' heads were designed to imitate the shape of a dead Neimoidian's skull. In this way, they were intended to strike fear into an enemy's heart. In addition, their bodies vaguely resembled those of the Geonosians.

B1 battle droids were physically identical to their direct predecessor, the OOM-series battle droid; unlike OOM models, however, they were not color-coded according to function, if any. However, some were painted with different colors to blend into a certain environment.

B1s were usually slaved to a central control mainframe located on a remote starship or some other well-defended facility. However, this could lead to massive failure if the central control mainframe was destroyed, such as during the Battle of Naboo, in which Anakin Skywalker destroyed the Droid Control Ship. The monumental defeat at Naboo spurred interest in independent battle droids, and this technique gained ground following the battle.In extreme cases, the droids would deactivate the electromagnets that kept their limbs attached. During the Clone Wars, clone troopers learned to aim at the hips, torsos, and arm joints of the B1s to quickly destroy them.

B1s were designed for cheap mass-production. As a result, they were very flimsy and vulnerable, but were capable of swarming an enemy with their hugely superior numbers. Other models, like the droideka, B2 super battle droid, grapple droid, and B1-A air battle droid, were more expensive.

Battle droids used E-5 blaster rifles, blaster pistols, and thermal detonators in combat. They spoke in a high-pitched monotone. The voice varied between units around the time of the Battle of Naboo, and at some point during the Clone Wars their voices were uniformly changed to a more high-pitched version.

Although they appeared to be weak, some B1s were able to take down an enemy in hand-to-hand combat as seen in the Battle of Grassy Plains where some battle droids were able to take Gungans one on one.

Although the earlier generations were entirely dependent on Central Control Computers, post-Naboo models featured some degree of independence and personality. Many older droids that were originally reliant on Control Computers developed personality quirks and a tendency to excessively comment on their situations
