What is one of the most important documents reviewed in a promotion board?

The Soldier's Enlisted Record Brief (ERB) is one of the most crucial documents reviewed during a promotion board because it provides a comprehensive summary of a soldier's career and accomplishments. The ERB includes essential information such as military education, awards, promotions, assignments, and other relevant details that reflect the soldier's performance and potential for further responsibilities.

The board members rely on this document to assess not only the soldier's qualifications for promotion but also their readiness for the next leadership position within the ranks. An accurate and updated ERB can significantly influence a soldier's chances for promotion, as it encapsulates their military achievements and service record succinctly for board evaluation.
