Who maintains the OML for Soldiers promoted to staff sergeant (SSG)?

The correct answer is that the Officer Management List (OML) for Soldiers promoted to staff sergeant (SSG) is maintained by the Commander of the Human Resources Command (HRC). This is because HRC is the authority responsible for overseeing the promotion systems and managing personnel actions for the Army. They ensure that promotion boards are conducted according to established policies and that the lists of eligible Soldiers are compiled and maintained properly.

In the context of Army promotions, the role of the HRC is crucial, as they provide the framework for the evaluation and selection processes that determine which Soldiers advance to the next rank. They utilize various evaluation criteria and data to create a fair and equitable OML.

The other options may play important roles in the promotion process at different levels, but they do not maintain the OML themselves. For example, the brigade commander and the regimental commander may have influence over promotions within their commands, particularly in terms of recommendations, but the official management of the list falls under the purview of HRC. The platoon sergeant may provide direct input regarding a Soldier's performance but does not have the broader responsibilities for the OML at the level managed by HRC.
