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 of the Canadian Armed Forces. It is named for Princess Patricia of Connaught, then daughter of the Governor General of Canada. 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 attached to 3rd Canadian Division; as such it serves as the "local" regular infantry regiment for much of Western Canada. The Loyal Edmonton Regiment (LER), a Reserve Force battalion, is affiliated with the PPCLI but is not formally part of it. As part of this affiliation, the LER 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 (1 CMBG) for the Regular Force and the 41 Canadian Brigade Group (41 CBG) 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.
