J-1 proton cannon

J-1 proton cannonsStar Wars: Absolutely Everything You Need to Know were a form of droid anti-aircraft cannon that fired proton bombs. They were used by the Confederacy of Independent Systems during the War of the Ring against the Galactic Republic. They were deployed by the Separatists on Arnor, Isengard, and Anaxes.
==History==
During the Confederacy of Independent Systems's occupation of Arnor, the tactical droid, TX-20 and his battle droids set up a battery of five of these proton cannons in the city Rhudaur. When the Grand Army of the Republic attempted to land, the cannons were able to destroy one of the three assault ships. The cannons were then destroyed when Jedi General Sam Gamgee hijacked one, and proceed to fire on the others. During the Second Battle of Isengard, they were used to stop Republic forces from reaching the primary orc foundry. A proton cannon used against the Republic ships during their landing phase was taken out by BTL-B Y-wing starfighters. After their ground forces reached Gap of Rohan, Jedi General Frodo Baggins led his Padawan—Jedi Commander Eowyn—and clone troopers into the enemy lines, where they used Electro Magnetic Pulse grenades to take out the scanners on proton cannons. This allowed All Terrain Tactical Enforcers to enter without incident and take out the Geonosian defenses, including the proton cannons and the shield generator. The cannons also saw action at the Battle of Anaxes, which turned out to be a key Republic victory during the Middle-Earth Sieges.
==Behind the scenes==
The J-1 proton cannon first appeared in the opening newsreel of The War of the Ring: Season One episode "Innocents of Arnor." They later appeared in the unfinished storyreel of the episode "Unfinished Business," as well as its completed Disney+ adaptation.
