Battle droid

"Do not confuse me with one of your mass-produced, fall-in-line, 37-percent kill-rate-at-best, military drones."

- AD-W4, on Separatist battle droids

Battle droids, also known as combat droids, clankers, or battle bots, were a type of droid designed for combat. Over the years, many different models of battle droid were been utilized by various factions throughout the galaxy. One such faction was the Confederacy of Independent Systems, which used a number of different models of battle droid during the Clone Wars to make up the Separatist Droid Army. Under the command of General Grievous, varying models of battle droid fought against the Galactic Republic's clone troopers until the final days of the war, when the Confederate battle droids were deactivated by the Galactic Empire.

Clone Wars
"A Republic military presence is the only sure defense against the Separatists.''" "Even extremists can be reasoned with." "''Perhaps if one can be heard over the clanking of their battle droids."

- Obi-Wan Kenobi and Satine Kryze

During the Clone Wars, the Confederacy of Independent Systems used a variety of battle droids in their droid army. These droids, including B1 battle droids, which were the main infantry of the Separatists, B2 super battle droids, and droidekas, were produced in large factories on planets such as Geonosis. The Separatist Droid Army was lead by the Kaleesh cyborg General Grievous. Droids like the B1 battle droid were ineffective in small numbers, but they had the ability to overwhelm enemies in large groups. Battle droids were led by commanders such as Grievous or Asajj Ventress, and organic officers could be assisted by specialized OOM command battle droids. T-series tactical droids and super tactical droids also commanded battle droids throughout the Clone Wars, and these units could assist organic leaders. One super tactical droid was Kalani, a general who led Confederate forces against insurgents on Onderon, but, after the Onderonian Civil War, Kalani escaped to Agamar.

The main enemy of the battle droids were the clone troopers of the Galactic Republic. The troopers were able to think independently and creatively, while battle droids like the B1 were "dim-witted" and easily taken down by clones. However, the battle droids of the Separatists outnumbered the clones, and Count Dooku once claimed that clones were outnumbered one hundred to one. During the war, clone troopers, and even some of the Jedi, referred to battle droids by the nickname of "clankers."

Age of the Empire
Although battle droids were outlawed by the Galactic Empire in the wake of the Clone Wars, companies such as Holowan Laboratories and Arakyd Industries were able to evade the ban by having their products reclassified as security droids.

Battle droids remained active on Agamar due to the intervention of Kalani, who was able to block the deactivation order initiated by Darth Vader after he killed the Separatist leaders. When the Empire arrived on Agamar, Kalani was able to flee with several B1 battle droids.

Galactic Civil War
Later, during the Galactic Civil War, Temmin Wexley owned a modified battle droid named Mister Bones who acted as a companion to him. After the rebellion on Akiva in 4 ABY, the two joined the New Republic and Wexley's mother Norra Wexley in the fight against the Galactic Empire. Mister Bones perished during the Battle of Jakku in 5 ABY.

New Republic Era
"I'm R0-GR— last of the B1 battle droids, nearly decorated veteran of the Clone Wars, and oft-disputed hero of the Rebellion. But you can just call me Roger."

- R0-GR

One B1 battle droid, R0-GR, came to serve under the Resistance and write "droidography," a guide to the various models of droids in the galaxy, to teach organics more about the droids they interacted with. R0-GR also stated that he was the last B1 battle droid, but he had learned of the existence of Mister Bones, and this lead R0-GR to say that his statement might have not been entirely true.
