China picks its lowest-scoring officers to command nuclear submarines

• Chinese submarine officers — except for engineers — tend to have the lowest entry exam scores.
• The lack of selectivity is remarkable. Submarines are likely to be critical in a conflict. 
• The Chinese navy seems to have doubts about its ship and submarine commanders.

The job of commanding a nuclear submarine should go to smart and well-qualified officers. Or at least that's the case in Western navies.
