Human performance teams (HPT) delivering a wide range of services within military unit communities serve as a model for advancing business practices in support of the 2018 National Defense Strategy. Relatively new, the demand for these embedded professionals continues to grow in response to its favorable proximity, community-based design, operationalized delivery system, and adaptive business practices. However, many civilian professionals come from diverse disciplines of specialties and experiences. As they integrate into unit communities, it becomes known that many do not possess formal training or experience working with the US military or its Servicemembers, delivering community-based services, operating in the capacity of a force multiplier, or culturally adapting their professional skills. Given the steep learning curve in transitioning from a conventional delivery model to the military embedded model, even newly minted military health and performance professionals may be underprepared when they arrive at their assigned military unit communities. In this article, we examine the military's embedded health and performance service delivery model. We add specific focus on those critical "embedded" professional competencies and skills foundational to establishing and sustaining thriving service delivery. We then offer strategies and tools collected from embedded health and performance professionals currently serving in military unit communities across the Department of Defense (DoD). Finally, we provide a rationale for the need for embedded competency training to improve the preparedness of professionals who are currently serving, will be serving, or have a general interest in serving as an embedded professional within DoD military unit communities.
