This jacket is a Canadian manufactured, 5 button jacket of British design. This is the most common pattern used overseas by the Canadian Expeditionary Force. The jacket has a stand and fall collar, secured by hooks and eyes. Cloth reinforcements on the shoulders are clearly visible, these are commonly known as "rifle pads" but were intended to protect the uniform from excessive wear by web equipment braces. Breast pockets are pleated, with straight edged flaps.
The collar badges are miniatures of the Canadian Military Police cap badge, brass CANADA and MFP titles are worn on the epaulettes. Buttons are the Canadian General Service pattern. A whistle is carried in the left breast pocket, attached to a lanyard on the left shoulder. A Good Conduct chevron and a single brass wound stripe are worn on the left cuff. A red and black overseas pattern MP brassard is worn.
The belt equipment consists of a Staff Sergeant's Pattern waistbelt and brace supporting an open top revolver holster and cartridge pouch. The revolver is a .455 calibre Webley Mk VI.
