Military deployments are stressful for service members and partners. Communication is an important factor in trying to maintain a relationship during these separations. This article presents a brief overview of communication in long-distance relationships for context, then reviews articles on communication during military deployments. This review reveals that emerging technology has resulted in an increase in the ability to communicate during deployment, although some studies suggest that access to such technology may vary. The few empirical studies that examine new communication technologies have found that different media (e.g., video calling vs. letters) may serve different functions in communication during deployment (e.g., facilitating problem discussion vs. providing tangible reminders of the partner). Military specific concerns, such as restrictions on communication and the potential for communication to distract service members from their mission, also appear to be important factors. The article concludes with clinical and research recommendations.
