Excellent point - if you look a tthe MAXAR picture you can see the lines where the river comes overt the gravel - either monsoon or glacial melt must flood most of that site. They got a truck in (you can see it) probably by driving down the riverbed - OK now but... and I can't see any "gun positions". Its hard to ID exactly where that site is on GE but it's clearly an escalation.
On the other hand " in place of the observation post that was destroyed by Indian troops in the bloody clash of June 15th" - which suggests it wasn't exactly one -sided...........
