The Battle Rifle-12, more commonly known as the BR12 Battle Rifle, was a firearm used by the United Nations Space Command and later the United Federation to Restore Humanity. Introduced in 2558 with the goal of phasing out the BR55 series, producibility was limited and the two similar weapons were used to together until the BR55's official retirement of its final variant, leaving the BR12 as the temporarily uncontested service battle rifle.
