The footage is totally real & verified by me.Fake.
In the last clip it was clear Indian soldiers were grouping together for charging towards the cliff which is why the video was abruptly cut off after only 20 seconds.
Anyways as per geolocation this feature is clearly located on Chinese side of LAC (even as per the India's own version of LAC); which means Indian troops successfully crossed into Chinese side of LAC.
Also this footage was from Sept 01.
Do you have the footage from sep 1 as you claimed?
