For that particular study we're trying to understand a diversity of experiences. We want to be able to have an open recruitment to see, during a period of time, who will be releasing from service. Then people can elect to join the study, recognizing it's going to be a commitment to the two and a half years with three different interview points. We will aim to have some representation across categories like the service element. Right now our plan is to be able to recruit the majority who will be coming from the army because that would represent the population. The next largest group would also be the navy and air force. We will also make sure we are capturing the experience of those who participated in the armed forces as reservists.
We want to be able to understand a variety of experiences, within the study. We'll have some categorization across things like the region of the country they are releasing from. We have to make sure that different experiences around language are represented in terms of English or French. We need to make sure that males and females are represented as well. It will depend on who is releasing within a given time frame, because if you have three-year study, you only have so many people whom you can expect to be releasing during a given time frame. We will look at about 100 of them, planning of course that we may lose some of them over the course of the study. Continued engagement in longitudinal studies is hard to maintain.
