A Casualty Assistance Officer (CAO) is a military member assigned to support families of service members who have been injured or killed. Their primary role is to provide guidance, information, and emotional support during a difficult time. CAOs help families navigate the benefits and resources available to them, ensuring they understand their options. In addition to offering practical assistance, CAOs also serve as a liaison between the family and the military. They communicate important updates and help coordinate any necessary arrangements, such as memorial services or funeral planning, ensuring that families receive the respect and care they deserve.
