What do the last two numerals in a billet number on the watch, quarter, and station bill indicate?

The last two numerals in a billet number represent section seniority within the context of the watch, quarter, and station bill. Understanding this aspect is crucial because it helps streamline the assignment and recognition of personnel responsibilities on board a vessel or within a unit. Each section can have multiple positions filled by personnel, and the seniority indicated by these numerals typically reflects the rank or order of importance among those assigned to the same section. This hierarchical approach ensures clear leadership and accountability, facilitating effective organization and communication during operations. It is a vital component of maintaining operational efficiency in a military environment.
