First of all there is no proof that this incident is as Pakistan claims.
Thar said the LoC confrontation showed Indian Army firepower is really intense.
Since 29th September atleast 27 Pakistan Army soldiers and 45 Pakistani civilians killed by Indian Army assaults along LoC.
Additionally 66 Pakistani soldiers were injured along with 139 Pakistani civilians in this assaults.
Compared to this, only 14 Indian soldiers and 12 civilians killed in Pakistani firing.
Pakistan Army is simply unable to match our firepower.
