Yes. that actually means, first cordon off, is first drop off of the tank / missile first stage completion and the second cordoned means the warhead impact, target hit....and that total distance between first and second is 2300 km. But then, you also need to add the distance where the missile is fired off from, Northern/Central Punjab. So from launch site Northern/Central Punjab to first cordoned off area and it will be around 4500 - 5000 km total launch to final target . in it?
The most likely launch site would be somniani...
