Fuchs asked:
What's the share of Muslims in the Indian army?
After sometime researching via Google it appears that:
1) no official figures for today exist
2) in 1947 Muslims accounted for 30-35% of the army
3) 13% of Indians are Muslim
4) reported in 2011-2012 3% of the army were Muslim, approx. 29k

I find that a rather low number, especially since I've seen reports on locally recruited Kashmiri infantry units.

As they say I know someone who should know, so will ask.
