Absolutely. We speak of operational stress injuries exactly for that reason. It was understood that to talk about mental illness within the military had such a large stigma that individuals would not come forward to access treatment or any other services. So DND coined the term “operational stress injury” so there was an understanding it was related to operations; it was like any other injury, physical or mental: it's an injury and it was related to the stress related to the operations. Just that nomenclature has gone a long way, especially within the military and the veteran community, to reduce the stigma associated with mental illness and to allow people to come forward to receive the services they require.
