Certain professions carry a risk of experiencing traumatic events and sometimes developing Posttraumatic Stress Disorder (PTSD). Researchers have been working on strategies to prevent professionals in those fields from developing PTSD. Recently, there has been a focus on applying technology that supports these preventive strategies, especially in a military context. This chapter provides an overview of the state of the art in technology-supported resilience training for military professionals, which has considerable common ground with the interdisciplinary field of human computer confluence (HCC). The effectiveness of these technologies and the resilience strategies they support are reviewed through the literature.@en
