The success of the military is significantly supported by highly effective collaborative teams. While much is known about successful military teams outside the context of healthcare delivery, considerably less attention has been paid to teams working in patient care. Thus, this supplement has explored the features of successful military interprofessional healthcare teams (MIHTs). In this summary paper, the authors discuss what this supplement's investigations have taught us about MIHTs and offer a series of proposed future investigations of MIHTs and their role in military healthcare.
