The article analyzed the impact of potentially morally injurious experiences on Canadian Armed Forces personnel deployed to Afghanistan. Potentially morally injurious experiences affect a person's post-deployment psychological distress and become a motive for leaving the force. In the life of military personnel, there are different stressors and unique challenges that play a role in the vulnerability of them experiencing psychological disturbances. Facing highly traumatic experiences such as traumatic deployments and being deployed to high-threat locations can lead to major depressive disorder (MDD), anxiety, posttraumatic stress disorder (PTSD), aggressive behaviors, suicidal ideations, and more. The studies being conducted here allow for more knowledge on how to properly create better-suited training and educate individuals in the military to avoid facing such high moral adversities.
