[Star Wars] Does the empire only hire humans as storm troopers? If so, why?

Watching Rouge one this weekend it struck me how a large portion of the rebel forces is made of non humans even some high ranking ones (Admiral Akbar) yet it seems that there are no non humans in the imperial ranks that we know of unless some of the stormtroopers are in fact humanoid. It doesn't make sense to block out such a large portion of the galaxy's population, is this a prejudice policy or is there a legitimate reason?

There are a couple of factors here.

One is that the empire is xenophobic, and as such prefers humans when possible (you can see this in their choice of non-stormtrooper officers as well).

Another is that the storm troopers are based on the clone troopers, which were all human (mandalorian specifically) as they were simply clones of Boba Fett. the empire may have wanted to hold on to the reputation of the clone troopers and thus made them as similar as possible, thus being exclusively human.

The third is that the stormtroopers are extremely disciplined ('only stormtroopers are so precise') and having a consistent universal uniform and weapons allows them to generalize training, rather than having to adjust on a person to person basis like they would if they accepted non-humans.


The first reason is the actual reason, the second puts tradition behind it, allowing people to feel justified in their xenophobia, and the final allows them to give a logical reason for it to people who disagree.
