Never fails...
More delusions of the "glory" of a past military career. The probability is high that this superior being relished in issuing orders to some 18 year old kids and this gave a sense of well-being.
But.. with most delusions... nobody gives a fuck in reality and sure ain't going to take orders from a total idiot...
Where there is a personality deficency, some join law enforcement and prison services to quell their desires for superiority - some join the military....
We can't all be perfect.
