In the rest of the military, however, similar French-speaking units were not created. Among the justifications for this policy were the predominance of the radio, and the fact that the technical instruction was only available in English. The 12th Armoured Regiment (Three Rivers Regiment), originally mobilized by the francophone militia unit the Three Rivers Regiment (Tank), was reorganized and fought as an English-speaking unit. Many French-speaking soldiers were sidetracked in this process. One of the most famous was Jean-Victor Allard, who demanded a transfer from the Three Rivers Regiment to the Infantry; he went on to become a brigade commander in Northwest Europe and then in Korea, command a British division in NATO and subsequently become Chief of the Defence Staff of the Canadian Armed Forces, where he took pleasure in creating the first French-speaking brigade.
