Of the eight infantry battalions recruited by the SALH's predecessors, only one entered combat as a unit. The 31st Battalion, CEF, landed in France in September 1915 with the 2nd Canadian Division. It was awarded 22 battle honours, including such notable actions as Vimy and Passchendaele. The other seven battalions – 9th, 66th (Edmonton Guards), 113th Battalion (Lethbridge Highlanders), CEF, 138th (Edmonton), 175th (Medicine Hat), 187th (Central Alberta) and 202nd (Sportsman's) – were broken up for reinforcements in England.
