Abstract: Military mental health providers will find themselves evaluating and treating service members for trauma and stressor-related disorders across various settings, including U.S.-based military hospitals and clinics or in the operational setting deployed at sea or abroad. The use of a psychoanalytic approach can be very helpful in evaluating and caring for service members who present with trauma and stressor-related conditions and assist in the patient maintaining good functioning in garrison or a challenging deployed setting. Maintaining the therapeutic frame and managing boundaries in the deployed setting is crucial to avoid development of potentially harmful multiple relationships. Development of a strong therapeutic alliance and monitoring the transference–countertransference matrix is crucial in forming an important foundation to the work.
