In Star Trek Discovery there is a species of alien who evolved as prey to the other primary species of their particular world. On the Shen Zhou they have a Lt Commander (Lt. Saru) who is a member of this alien race and is a very fearful, almost cowardly, person who wants to run away from danger at any opportunity.
So the question is: Why and how would a person like this ever
- enlist for a Command position and
- even get through the academy far enough to reach any rank near enought to take the bridge in command?
