Rehabilitation is possible in the case of a number of mental health problems. One thing is rather disturbing, however. Unlike other armies, the Canadian army does not give people a desk job if they have had PTSD. It might take a number of years, but the army does not keep people it cannot deploy someday. Efforts are made to try to place these individuals in other positions, but ultimately, the Canadian army is composed of people who can be deployed. That is a choice that was made. I think that also explains why the military does a great deal of recruiting, but also why there tends to be a rather high turnover. In my opinion, there are advantages and disadvantages to this. I would say that one of the disadvantages is the loss of some military expertise.
