I was going to post this on Indian Military thread but decided to post on here instead.
It looks like the video that was embedded on the Twitter/X came from this YouTube Channel operated by an Indian soldier. I don't know if the person remains in active duty or not, but he has uploaded a bunch of videos encountering PLA.
Example 1
Example 2
Example 3 (this is the video that's going rounds on Twitter/X) I didn't know it's part of the Geneva convention to continuously beat an already captured soldier, then carry the soldier like a dead pig/cattle with no regard to safety.
However, I find the video somewhat amusing because 3 Jai Hind super strong soldiers couldn't lift a super weakling chinky soldier when according to their self-invented legend, a single Jai Hind super soldier took on and killed more than a dozen PLA soldiers before finally getting KIA.
Example 4 (Another video showing an apprehended PLA soldier)
