Comlink booster pack

A comlink booster pack was a piece of technology worn on the backsides of most B1-series battle droids. It varied in design and usage for various battle droids, with differences between B1 droid sub-models, the droids' military position and affiliation, as well as specific groups of droids.
==Description==
===Manufacture and design===
B1-series battle droids with rust-brown plating at the Geonosis primary droid foundry's assembly lines were each installed with a comlink booster pack. The booster pack was a piece of technology that most B1-series droids wore on the back of their torso.Ultimate Star Wars
====Design differences====
The shape and appearance of the pack differed between those worn by B1-series droids produced for the Trade Federation Droid Army and B1 droids manufactured for the Separatist Droid Army. Two antennae of differing length extended from a Trade Federation droid's booster pack when the battle droid was activated by a central computer, whereas some Separatist droid's pack featured only one antenna. However, Separatist B1-series battle droids present at the First Battle of Geonosis, which were manufactured by the natives of Geonosis, had two antennae of differing length.
The booster pack was fit over twin railings on the backs of Separatist battle droids, and Federation droids' packs featured numerical markings identifying the droid wearing it. Whilst a battle droid without the pack holstered their standard E-5 blaster rifle on one of two railings installed on the back of their torso, a Federation battle droid equipped with the booster pack placed their blaster rifle aside the pack, with booster pack–equipped Separatist droids of the Agamar garrison—who remained on the planet Agamar during the Galactic Civil War after crash-landing on the world during the Clone Wars—instead storing their blaster rifles at the back of the pack.
==Usage==
The antenna was not extended for Separatist battle droids aboard the bridge of a Munificent-class star frigate participating at the Battle of Quell. Some droids stationed aboard the bridges of the Confederacy Munificent-class frigates commanded by Cad Bane at the Battle of Devaron lacked the booster pack entirely.
Of the OOM-series battle droid line, only some OOM command battle droids wore a booster pack. Some Separatist OOM command battle droids, such as 224, had a yellow, circular marking on their booster pack, although it lacked the numerical markings that identified the droid's designation. OOM-9, the Trade Federation field commander of the Battle of Naboo against the native Gungan population, lacked a comlink booster pack, although the OOM command battle droid had the pack's two antennae installed on the back of his torso.
==Behind the scenes==
Comlink booster packs evolved from Doug Chiang's concept of B1-series battle droids wearing jetpacks while working for the 1999 prequel trilogy film, Star Wars: Episode I The Phantom Menace, in which the booster packs first appeared.
