Most of it is covered by what others have already said bro.
For one, I'm not really sure about which radio that is, but it's pretty obvious that the radio cannot be bought off the shelf by the operator himself... So it could be an indication that such radios are entering service with Indian SOF.
It seems like one of those PRC-152 (Looks like, I'm not really sure which one it is) SDR radios which US SOF guys have attached to the rear of their plate carriers with attachment via a PTT into their earpiece. The earpiece is still shitty, but the radio seems like a good start.
Apart from that, the plate carrier looks solid. Rides high up on the chest.. pretty contemporary... Looks lightweight and no frills as well.. so ergonomic in that sense too.
