Treatment of Chronic Anger and Aggression Following Military-Related Betrayal

The goal of this clinical trial is to learn if a treatment designed to deal with anger and aggression from a past betrayal will work. The study will be done on active duty military service members and veterans aged 18 or older. The main questions it aims to answer are: * Will participants be satisfied with the treatment, and is the treatment feasible to do in a military outpatient setting * Will the treatment help with anger and aggression issues. Researchers will compare differences in groups that have different wait times (2-, 3-, or 4-weeks). Participants will complete surveys before, during and after the treatment. The treatment will be 14 modules given twice a week. About 1 month after treatment ends, surveys will be taken again.
