Presumably, the Royal Army was formed fairly soon after the founding of the Kingdom of Acorn. The vast majority of troops in the army would end up being Bears, either the large Grizzlies or their smaller Brown Bear counterparts. After the devastation of the Great War, the army was further decimated by the rise of Dr. Robotnik. Though Armand D'Coolette led a staunch resistance, much of the army was among the early casualties-either killed or Roboticized-during the First Robotnik War. (CSE)
