As I said previously, this study is a first and the only one, to our knowledge, that is based on a representative sampling of the Canadian Armed Forces. Perhaps the Americans and the British have not yet dared to do such a study. All we have access to are sub-samples and subsections. We never know these are representative of the whole population. Therefore, it is difficult to make comparisons.
