Russia and Ukraine

[Anomalocaris]

more likely there is a systematic process improvement program and performance based assignment and promotion that is weeding out incompetent officers and trialing new doctrines. 

Dynamic, competent officers willing to take responsibility are the ones who tend to go up to the front line to personally take charge of serious and critical situations where they can get killed.   Grifters would find a way to be far away from where things might get gnarly, and head for  some place safe, and preferably where they can play act in public eye,  instead.

So officer attrition through casualty might be expected to do the opposite by killing more competent officers abs leaving a higher percentage of grifters.

Retraining officers to perform better during a war is pretty iffy. Eleven weeks to change a mindset is also pretty sketchy.

High casualty rate amongst officers might have a salutary, mind focusing, lessons embracing effects on those who might wish their turn to not come too soon.
