Vehicles of the Indian army have no green, white and orange markings or anything of that sort, but they can be identified by the white numbers on a black background that appear on the front and rear, preceded by an upwards-pointing white arrow. They've been marking their vehicles this way since independence. I have some pics of Indian army Sherman tanks, jeeps and trucks during the Hyderabad War/Operation Polo marked with this arrow-and-numerals combination.
There's never been a kit of any Indian military vehicle before this, as far as I know, although a few kits of Indian aircraft and aftermarket IAF decals are available.
