Western Armies (American, British, Canadian, French, German, etc.) have traditionally had very strong NCO Corps. Senior leadership entrusts much responsibility to these NCO's and it pays off on the mission end.
Eastern Armies either entrust too much authority in their officer corps, or Senior leadership. In authoritarian countries, many Generals hate have subordinates that have a strong base of knowledge- they're afraid that they'll get overthrown. Other armies have a contempt for ALL enlisted men, not just privates.
