The professionals in the Army know what they are doing
A lot of fighting happened in 1971 December on the Western sector on the LOC
Secondly from December 2001 LOC skirmishes started and continued till
the Ceasefire in 2003
Not in Kashmir. Along LC it has been just minor raid on each others posts.
So snow is not a factor
Hmmm ... Tell that to the soldier who trudges in 36 -40 feet of snow in avalanche prone reaches of LC.
