Collaborative intervention: a model for coordinated treatment of mental health issues within a ground combat unit.

Involvement in combat imposes a psychological burden that affects all combatants, not only those who are vulnerable to emotional disorders or those who sustain physical wound distress. This burden of combat is also carried by the families of those who go to war. Although most ground combat units have a medical officer as well as a chaplain assigned to them, they do not have a mental health counselor or psychologist.
