I completely agree with the latter half of the statement - The officer cadre of the Indian army used to come from well educated, well heeled, at least proper middle class families, with long lineages. Now, it probably comes from the lower strata of society. This is not a bad thing, but how many graduates of elite schools and universities even competing for selection to the academies ??
Just look at any ex NDA (specially army), still young in service, he won't be able to speak 2 proper sentences, he'll try to speak with an accent with a fouji tongue, but will fail miserably. OTA alumni are much more eloquent, and well read.. having come from the civvy street.
Army should urgently look at improving the quality of officer intake, get some well read intellectually inclined people from best schools into NDA, not focus on Sainik school types, whose world view is limited.
Just see what a clown sahani made out of himself in the recent podcast.. although, neither he nor most of his followers will realize this. No depth beyond the very tactical level platoon ops.
