Cap Badge - 175th (Medicine Hat, Alberta) Battalion, CEF The 175th Battalion, CEF, was a unit in the Canadian Expeditionary Force during the First World War. Based in Medicine Hat, Alberta, the unit began recruiting during the winter of 1915/16 in the Medicine Hat district. After sailing to England in October 1916, the battalion was absorbed into the 21st Reserve Battalion on January 10, 1917. Perpetuation of the 175th Battalion was assigned to the Alberta Regiment in 1920. When this regiment split in two in 1924, the South Alberta Regiment carried the perpetuation. The South Alberta Regiment merged into the South Alberta Light Horse (29th Armoured Regiment) in 1954, and this regiment (now simply the South Alberta Light Horse) carries on the perpetuation of the 175th Battalion.
