B1 battle droid

"Roger, roger."

- Typical response of a B1 battle droid

The B1 battle droid, sometimes referred to as the standard battle droid, was a model of battle droid manufactured by Baktoid Combat Automata and Baktoid Armor Workshop. B1 battle droids saw extensive service during the Trade Federation's invasion of Naboo and the Clone Wars. Following the defeat of the Confederacy of Independent Systems, B1 battle droids along with the Separatist Droid Army were deactivated by the Galactic Empire.

History
B1 battle droids were manufactured by Baktoid Combat Automata and Baktoid Armor Workshop during the last decades of the Galactic Republic. Designed to resemble their Geonosian creators, the Trade Federation made extensive use of B1 battle droids and utilized them as their military force during the Federation's invasion of Naboo. They were the succesors to the OOM series battle droids, units that were physically identical to the latter, but were forced to operate with the help of a droid control ship, while the B1s had the ability to act independently.

Ten years later, the Federation provided B1 battle droid forces to the Confederacy of Independent Systems, which were used against the clone army of the Galactic Republic during the Clone Wars. During the Clone Wars, B1 battle droids were the most common form of battle droid. They would charge towards their enemies, firing their blasters. They had three fingers on each hand. They were vulnerable to EMP weapons, such as the electro-proton bomb. These battle droids were able to pilot and operate Single Trooper Aerial Platforms (STAPs) and Armored Assault Tanks (AATs).

Battle droids were outlawed by the Galactic Empire in the wake of the destructive conflict. Orders were given to stormtroopers to shoot and destroy "clankers" on sight. In 2 BBY, the super tactical droid Kalani commanded several battle droids and droidekas at a wrecked Separatist supply ship on Agamar. These droids fought with the former Clone Captain Rex and the Lothal rebels before joining forces with them to escape the Empire.

Battle droids in the galaxy
Some notable B1 battle droids included the OOM command battle droids OOM-9 and B1-268. During the Galactic Civil War, the modified battle droid Mister Bones served as a companion to Temmin Wexley. Following the Rebellion on Akiva, Mister Bones along with Temmin and his mother Norra Wexley joined the New Republic.

Behind the scenes
B1 battle droids appeared as antagonists in several Canon media including the Prequel trilogy, The Clone Wars movie, The Clone Wars television series, Star Wars Rebels, and Chuck Wendig's novel Aftermath. In addition, they have also appeared in several Legends media and literature including Genndy Tartakovsky's Star Wars: Clone Wars television series and the Dark Horse Comics Star Wars: Republic series. The battle droid Roger also serves as one of the protagonists of the non-Canon Disney XD television series LEGO Star Wars: The Freemaker Adventures.
