Sir your opinion on this, why not Indian troops or BSF retaliate.
Thank you for the tag sir.
Firstly, few things to be clarified. The transgressions are mutual occurrences since if you look at the topography due north east of Tawa and Walong in North westerly direction, it is a watershed that exists.
As per mutual agreements under JWG, the area is not militarized and till early 90s ( when 1st JWG was formed) something called the 'billi patrol' or aggressive posturing by opposing patrols were a regular affair ( with instances of standby of artillery and other support elements); the 1967 Nathu La and Cho La incidents being pretty famous ones.
However, since the Macmahon line is not recognized by PRC, and Indian presence is in region, there is a tendency of such occurrences bilaterally .....
In 2013, I remember that the Chinese were surrounded in a matter of 2 hours by Ladakh Scouts and SF and the concerned brigades of the area (let's leave the units and brigades) were despatched with first and second line ammunition.
What followed was a long stand off and subsequent withdrawal of Chinese and de escalation.
This has resulted today in one Indian armored brigade having been airlifted into the region and enhancement of troop deployment to negate such instances.
The policy of both the Chinese and Indians is to keep testing and not to escalate, as had Chinese wanted to escalate, they are presently in a position wherein they will make significant inroads before being blocked due to the force levels deployed across in Tibet itself.
Won't read the blog as inaccuracies may exist.
But one example of Jelep La pass can be made.
The pass was completely held by India till 1995, whereupon it was mutually agreed to withdraw troops from east Sikkim as part of CBM, today the eastern shoulder is held by Chinese as they moved in shortly after de-induction.
There on, these incidents are again becoming regular and there is an equal response from India, namely quite often in Sugar Sector.
