> I've heard in the military officers that served in the enlisted ranks before commissioning are more effective and supported by their troops than those that come straight out of OCS

100% true. The difference is night and day.

Both with their own self confidence to lead a group of enlisted and specifically senior enlisted who in my unit, almost always would have had more front line combat experience than the officers, which meant knowing when to overrule and when to defer to their judgement.

And simply the day to day small and large decisions/choices both during training & deployment were always more informed when backed up with prior enlisted experience.
