As far as the Armata concept is concerned, it is nothing new. Despite what Russians advertise it on their brochure, it is merely an old wine in a new bottle.
US already tried this concept of unmanned turret in the 90s, with a modified M1 hull and a robotic turret, with crew seated in a armour capsule. But the US army rejected this concept in favour of conventional 3 man turret with the M1A1, M1A2 etc. The British also had a similar implemented project on their Challenger 1 hull with a robotic Falcon turret (for the Jordanian Army). But the British army rejected it in favour of Challenger 2.

Falcon turret
The Falcon turret is a modular turret which can be retrofitted on any 3rd generation tank.
As far as Indian Army is concerned, the concept of FRCV came up when the Army decided to go public about its requirement in 2017. After than they haven't made any statement to the media. The concept of FRCV is absurd and vague, as army has not issued any GSQR, but wants global designers to build the tank in India based on their own proposal, and transfer the IPR to Army, and it will be mass produced in India.
Then the Russians have started pitching in the monkey models of their Armata (which their own army is yet to induct in large numbers). The South Koreans are pitching in their K2 MBT. However absence of any concrete requirement stated by army, the project is bound to fail.
