Team building has been given increasing attention and applied in diverse disciplines in recent years. The purpose of this study was to determine the multiple dimensions to the application for the effectiveness of team building in the military units such as ROTC since not many existing literature has investigated this in such an expectedly high command culture. The data suggested that participants generally rated themselves to possess the knowledge, experience, and expertise for team building. Secondly, they predominantly considered ROTC as a self-managing formal team, and that leaders basically led their team assuming the role of an educator. Thirdly, the top three selected significance of competences in team building were establishing open communication channels, setting clear, measurable goals, and making assignments clear and ensuring competence. Finally, based on the inconsistency from data, it was suggested that establishing an open communication channel can be expected to integrate and improve remarkably the effectiveness and efficiencies of team building in ROTC.
