The Solar Liberation League was a radical branch of the Granzera Revolutionary Force Army. It is one of the antagonists of R-Type Tactics II: Operation Bitter Chocolate.
History
Mankind broke into two sides over an argument of whether the Forces should continue to be used; the Earth Forces, who used Bydo related technology, and the Granzera Revolution Army, who used technology that had nothing to do with Bydo. However, after both sides joined forces to find the culprit behind the man-made Bydo, they discovered that it was the Solar Liberation League; the Solar Liberation League was working on the Bydo Bind System, a larger version of the Control Rod system used to control the Force, that controls larger Bydo organisms and make do their bidding. The League was then defeated by the combined forces of the Earth Forces and the Granzera Army.
