Well, actually speakers blasting music is something we can also do to them, a small kerosene generator and two subwoofers are no big deal to procure and get atop the hill.
Play Taiwan national anthem in the loop and see their asses burning.
play back how them chinese soldiers who are forced into comunist part army and is not even given a good burial when they get killed by Indian Soldiers..and they are all gonna get killed for Xi's personal propaganda and personal riches.
IMO, chinese are psychologically weak and they dont have the stomach to digest some hard reality, the reason why CCP is continuously feeding them propaganda and putting them in the rat race must have tuned them too much into a certain comfort zone..
So when we hit china back with the same loud speakers, it will affect and damage their morale even more.
We have seen how rattled chinese felt and with their ass burnin rant on the SM, post Galwan incident and black top . The chiense govt themselves had to do some fake propaganda bullshit to calm the nerves.. i mean confuse the nerves and put the chinese back into lullaby.
Even on this forum, we have seen how chinese dance when confronted with reality..
Any counter measures from India on the same coin will hurt chinese more and devastatingly more on Psy ops.
