As we all know, PLA is well disciplined and they strictly follow rules of engagement, don't fire unless fired upon.
Alleged place of conflict is around the semi-circle shoreline on the south bank, where I believe PLA JLTV CSK-181 is accessible, as there's already a nearby road going up Black top from the north side.
If indeed Indian light infantry shot at the PLA's JLTV, alleged to be around 10 of them, and their truck mobile infantry, it would definitely be a bad day for them.
No doubt there would have been be a few backup PLA mechanized infantry in IFV's in close proximity behind the JLTV's, closely watching the whole thing with drones.
At least Indian troops would have been rounded up and pictures taken for posterity.
