Japan Liberation Front

The Japan Liberation Front (Or Japanese Liberation Front, abbreviated JLF) was prior to their destruction the second largest Japanese resistance organization (second only to the Black Knights after they were formed). They attempted to undermine Britannian Rule over Area 11 several times with limited success. However when Cornelia Li Britannia becomes the areas new governer, the provincial goverment began to persecute the terrorists more aggressively. As Cornelia was obsessed with eliminating even a minor threat, Britannian forces were brought in to search out and destroy the underground group. After finally locating the JLF main base high in the Japanese mountains, she attacked in what is known as the Battle for Narita. This battle would almost destroy the JLF, eliminating their headquarters and most of their leadership, such as the JLF commander Katase Tatewaki. They would ultimately be defeated in Port Yokosuka.

Military
The Liberation Front's military consisted of resistance soldiers and modified Britannian Knightmare frames, and was led by many surviving military Officers of Japan's orginal Armed forces. Many of these frames were provided by Kyoto House, other were stolen during their numerous raids. The Four Holy Swords were an elite unit to pilot their more advanced frames, and were used as an "Ace in the Hole" against Britannian forces.
