Universities are creating classes to train students in how to treat combat veterans and their families suffering from war-related mental health problems. As psychologically wounded troops return from the wars in Iraq and Afghanistan, the initiatives range from workshops to semester-long graduate courses, such as one on military culture next year at the University of Washington-Tacoma. The University of Southern California is starting a masterĂ¢??s program in which students will interact with holographic images of troops in distress.
