US Naval college has issued a report and used mostly Indian sources (like prasun gupta etc) and ironically even that report is shameful for India.
It pretty much destroys your narratives.
As the report mentions how 10 I'll equiped paramilitary troops, moved to occupy a peak, without any acclimatisation,winter clothes,rations with light weapons (rifles,LMGs etc) and held back combined assault by several Indian regiments and air strikes) inflicting heavy casualties on Indians for several weeks..
And had to withdraw and suffer due to shortage of food,ammo,disease (frost bite due to non availability of warm clothes to prevent from snow)... and shelter made of rocks and boulders.
Against over entire Indian divisions and airpower.
Any man worth his daily would salute their valour and grit.
