For that we have gone for K-9. It was planned only for western sector. But after its deployment in Ladakh, we have again raised an AON of 200 guns.I wasn't talking about towed arty in mountains,only in plains.In plains its suicide to use towed arty these days with drones and counter battery radars.
So we would be deploying K-9 in those heights too, but in limited numbers. So towed artillery is something which we can't ditch.
