A merchant mariner's temporary petty-officer appointment shows how wartime navies draw on existing experience. Basic sailors can be trained rapidly, and junior officers can be expanded when a service has adequate reserve and senior-officer pools. Competent NCOs are harder to generate because their authority depends on accumulated practical knowledge. This makes senior ratings a critical constraint on how quickly a navy can turn extra personnel and hulls into effective fighting units.

Why wartime naval expansion runs short of NCOs
A discussion of temporary wartime rank develops into an institutional lesson: navies can create basic sailors and junior officers faster than they can produce experienced NCOs.
