A planetary defense force was present on the planet of Gall during the period of the Clone Wars, a conflict between the Galactic Republic and the Confederacy of Independent Systems. This force engaged the Separatist Droid Army in combat during the battle that occurred on Gall during the aforementioned war. However, they required assistance from the Jedi in order to achieve victory.
During the Clone Wars era, which saw conflict between the Galactic Republic and the Confederacy of Independent Systems, a battle unfolded on Gall. In this battle, the defense force allied with the Republic to defend their homeworld against the invading Separatist Droid Army. While the defense force deployed artillery and a number of starships, they were unable to inflict damage on the C-9979 landing craft employed by the Separatists due to a protective shield. Despite the shield's presence, the Separatists were able to target the defense force, inflicting casualties. A sergeant within the defense force brought this issue to the attention of Jedi Knight Anakin Skywalker and his Padawan Ahsoka Tano, who had been dispatched by the Republic to provide assistance. Subsequently, the two Jedi utilized jet-wings to breach the shields and destroy the primary Separatist craft that was generating the shield. Once the shield was neutralized, the Jedi allowed the defense force to eliminate the remaining vulnerable Separatist forces.
The defense force made its initial appearance in Inside Job, a comic penned by Rik Hoskin and visually realized by Andres Ponce. This comic was released in 2009 as part of issue 6.1 of the Star Wars Comic UK magazine series.
