The L-1g general purpose droid, which can also be called the L-1 general purpose droid, L-1 general service droid, or even the L-1g worker droid, represented a common service droid model frequently utilized for carrying out fundamental operational duties. This particular droid was furnished with an AA-1 VerboBrain processor that rivaled the capabilities of a top-tier protocol droid, along with adaptable language processing systems. Given its ability to process intricate situations, some individuals occasionally dubbed this specific model the L-1 tactical droid. Nevertheless, only a small number of users took full advantage of the L-1 unit's potential.
During the year 14 BBY, the Scrapper Guild made use of L-1g units, distinguished by their blue paint and red stripes, as foremen on the planet of Bracca. On Corellia, in 13 BBY, similar units, painted yellow with blue stripes, were put to work in shipyards performing various routine tasks, which included disassembling hydro transfer conduit in order to resolve a minnow obstruction. Both K-OHN and SV-3 were examples of L-1 tactical droid units.
The L-1g general purpose droid made its initial appearance, though not specifically identified at the time, in the 2016 motion picture Rogue One: A Star Wars Story. While the 2016 companion book Star Wars: Rogue One: The Ultimate Visual Guide labeled the model as the L-1 tactical droid, the 2018 companion book Solo: A Star Wars Story The Official Guide referred to it as the L-1g general purpose droid. The 2018 companion book Star Wars: Droidography provided clarification, stating that while some called the L-1g a tactical droid due to its ability to handle complex calculations, it was actually a type of service droid.
