Frankly I was embarrassed to be tagged with those gentlemen there...but I do know that the missile's Block-III version has trajectory maneuver and steep dive endgame to take out targets hidden behind mountain ranges.And will also be useful against naval targets that are more difficult to defend against vertical threats.
In short the Brahmos block III confers upon the IA's artillery arm the ability to block mountain passes thereby bottling up ingressing forces.
Also our govt has approved the deployment of BrahMos missiles in AP to counter China's huge build of military infrastructure.
I hope I didnt go wrong....if I did then ignore it as I'm pretty dilettante. lol
