I recommend having a look at Jim Storr's books. He has nothing good to say about authoritarianism or low intelligence in senior officers. "Authoritarians tend to be bullies...the biggest problem, however, is that they are not good commanders and may well fail catastrophically in war...in major wars, the incompetents fail first. The authoritarians and excessively self-confident go, but go later."
He has several recommendations to deal with authoritarians. One item he often emphasizes is psychological testing, which he believes is capable of identifying authoritarian personality traits. Another is to routinely test commanders with demanding exercises (CPXs, CAXs, TEWTs, etc) - eventually the authoritarians will fail under pressure.
