Princess Patricia's Canadian Light Infantry

Princess Patricia's Canadian Light Infantry (PPCLI, generally referred to as The Patricias) is one of the three regular force infantry regiments of the Canadian Army. The regiment is composed of four battalions including a primary reserve battalion, for a total of 2,000 soldiers. The PPCLI is the main lodger unit of Canadian Forces Base (CFB) Edmonton in Alberta and CFB Shilo in Manitoba, and belongs to the Land Force Western Area; as such it is the "local" regular infantry regiment for much of western and Pacific Canada. The Loyal Edmonton Regiment is the reserve battalion of the regiment and carries the designation '4th Battalion, Princess Patricia's Canadian Light Infantry'.

The regiment is a ceremonial structure, and the four battalions are independent operational entities, under the 1 Canadian Mechanized Brigade Group for the Regular Force and the 41 Canadian Brigade Group for the Primary Reserve. Although the regiment carries the designation of 'Light Infantry', two of its battalions are mechanized infantry, and the unit has never been organized as a traditional light infantry regiment.

The PPCLI was raised on the initiative of Captain Andrew Hamilton Gault in 1914, to participate in the Canadian war effort for the First World War. It was the first Canadian infantry unit to enter the theatre of operations, arriving in France on December 21, 1914. The regiment has also participated in the Second World War, the Korean War and the War in Afghanistan, as well as in numerous NATO operations and UN peacekeeping missions. The regiment has received 39 battle honours, two mentions of the Commander-in-Chief and the United States Presidential Unit Citation.
