Outstanding officers with a strong individuality and intellectual curiosity get culled by the stubborn seniority system.
In his seminal On the Psychology of Military Incompetence Norman Dixon poses the questions: "How, if they are so lacking in intelligence, do people become senior military commanders? And what is it about military organisations that they should attract, promote and ultimately tolerate those whose performance at the highest levels brings opprobrium on the organisations they represent?"
Fortunately we have not had a major war in recent times to test the mettle of our commanders. But even in peacetime, many have, unfortunately, managed by their acts of omission and commission to bring opprobrium on our military.
The upper echelons of India's military are now visibly dense with incompetent and uninspiring leaders, who simply managed to get good ACR's year after year with bland obsequiousness.
They then go about expecting the same from their subordinates, and get it in plenty. Outstanding officers with a strong individuality and intellectual curiosity get culled by the stubborn seniority system, adopted from the bureaucracy.
