The comment did not come from me, but your own ex-Northern Command Lt. Gen. You might want to update him on how Indian Army wants to fight in AJK.But the next war wont be fought that way i.e. for every sq Km.
Even the 71 war wasn't fought every sq km.
India by passed other major towns in East Pakistan and reached near Dhaka by para dropping, then asked for surrender.
Indian military analysts say even Putin following a similar approach with Ukraine and paradropped special forces near the outskirt of kyiv to gain surrender of Ukraine.
Anyways, coming back to AJK, the point is, India wont be fighting in the mountains to capture AJK.
