ahh again you got that completely wrong!!i would strongly advice you not to post random b.s. in an international forum without a clear knowledge on a particular subject

we didn't construct an permanent bunker in that area,our jawans built some temporary shelters when they were camping there opposite to the PLA detachment.so technically we only demolished some tin sheds which had no significance at all.
now pray tell me why did your "invincible" PLA ran away with their tails between their legs after staying there for a couple of weeks!!
