What type of board primarily focuses on promoting soldiers based on their qualifications and performance?

The type of board that primarily focuses on promoting soldiers based on their qualifications and performance is the Promotion Board. This board evaluates soldiers' records, performance evaluations, and qualifications to determine their eligibility for advancement to the next rank. It assesses a soldier's capabilities, leadership potential, and contributions to the unit, ensuring that promotions are merit-based and reflective of each individual's readiness for increased responsibilities.

In contrast, a Disciplinary Board addresses issues of misconduct and may recommend actions for discipline rather than focusing on promotion. A Transfer Board typically deals with the reassignment of soldiers to different units or positions without a direct focus on promotion. Lastly, a Retention Board evaluates whether soldiers should be retained in service, which is separate from promotional considerations. Therefore, the Promotion Board is distinctly geared toward advancing soldiers who exemplify the Army's standards of excellence.
