Gasha 30mm canon is licensed by us. Using two such systems along with the sensors used upon Shilka upgrade.Gotta combine it with a 30/57mm cannon and a radar + EOS and put it on tracks, like a BMP-2. We can then replace Strela and Shilka.
I believe private companies are already doing that.
Fitting these things on a Arjun Chassis should help.
