I was very intrigued about a certain type of soldiers we saw patrolling N. Delhi’s subway during the Commonwealth Games: petite women wearing khaki soldier gear portraying mongoloid (aka “Chinese”) features with (beautiful) chiselled faces. Despite their tiny size, emphasized by the clearly too long assault rifles they carried, they looked very fierce soldiers, always standing and alert, making a great contrast when compared to the Indian regular (male) soldiers, that looked extremely bored always sitting and playing with their cell phones. We asked these women for directions 2/3 times and their serious faces always turned into very friendly smiles and gave all the information kindly. I finally asked where they came from: Nagaland
I had never heard about these (pretty isolated) regions, but since then I read about them and feel great curiosity/interest.
Wish you the best luck in your trip, I hope you’ll get there to see them by yourself.
PS: This post doesn’t help you much with info, since I know nothing; it’s just to encourage you to discover them; I’d be happy to get there, maybe one day. Btw, I found a picture on line of the Naga women soldiers during the Game... I paste it.
PS2: Don't miss Nepal if you can, I recenly read here that the 3 month "out-of-the-country" visa rule has been turned down (confirm it). Nepal is beautiful.
