I understand what you're suggesting. I wouldn't recommend that because I don't think that's exactly how it works. You can end up working in a variety of different areas, so you're not going to have a whole lot of people who are, at the get-go, declaring a career in veteran-specific psychology, for example. You wouldn't have a huge number of people who make that kind of clear and very defined career choice. I think the broader issue is that in training in disciplines such as psychology, medicine, or whatever, it's not the kind of counselling model where the expectation is that the healer should have the experience of the people they're going to help.
For example, for psychologists who choose to work in child abuse, or psychologists who choose to work with epilepsy, or psychologists who choose to work with dementia, it's the scientist-practitioner model, but it's where you're building on the body of work and you're definitely getting practical experience in your training working with that population but not necessarily personal experience. In many cases, it's not feasible and not the training model.
