The Panama Canal Division was a unit of the United States Army, established in order to ensure the United States could adequately defend the Canal Zone in Panama. When it was authorized in 1920, similar divisions were organized to defend Hawaii and the Philippines.
The commander of the Panama Canal Department, Major General Preston Brown, later determined that the defense of Panama would be better served by command groups representing the Atlantic and the Pacific. In 1932, the Army inactivated the division, keeping its Tables of Organization on file should the need arise to reactivate it. It never has.[1]
