Final answer:
The total end-strength population of a military rating refers to the number of personnel currently serving in that rating, while the CNP requirement is the number of personnel the Chief of Naval Personnel has determined should be in that rating for optimal workforce planning.
Step-by-step explanation:
The question refers to the end-strength population of a specific military rating compared to the Chief of Naval Personnel (CNP) requirement for that rating. End-strength population is the total number of personnel that are actually serving in a given military rating at a specific point in time. The CNP requirement represents the planned or authorized number of personnel for that rating, as determined by the Chief of Naval Personnel, who is responsible for manpower planning in the Navy.To understand the relationship between the two, one would need to look at the current staffing levels in a rating and compare them with the CNP's targets. If the end-strength population is higher than the CNP requirement, this might indicate an overmanned rating; conversely, if it is lower, the rating could be considered undermanned. Such information is essential for workforce planning and ensuring that the Navy has the right number of trained personnel in each rating to meet its operational needs.
