I've been interested in picking up one of Trump's T 90s. An Indian tank is kind of intriguing. I don't know much about T 90s, it looks like the only difference between Indian and Russian is the paint scheme? It doesn't look like the kit has any decals.

this T-90C is a pretty much stripped bared version, doesnt have shtora and some other electronics of the russian T-90A

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.

If Trumpeter doesn't provide decals for the T-90, it would be easy enough to get a blank white decal sheet and print some. Another modeler has finished this Zvezda T-90 in Indian markings. LINK
