Just to be clear, are you saying the army definitely did this in defense of the yellow shirt protesters? I assume your reference to RS means Red Shirts (pro-Thaksin forces defending the caretaker government).
Having lived in Bangkok and traveling back there often I think we all assumed the military would declare martial law and probably stage a coup at some point, but I am not clear at this moment whether they've officially thrown in with one side or the other. I guess it is still possible they will take over, restore order since the Yellows/protesters don't trust the police, and work with the election committee to determine a new election date. I am not so clear yet that the military has sided with Suthep and will insist on reforms before the next ballot (which I hope is the case since I detest Thaksin and all the incarnations of his TRT party).
I don’t know, I haven’t been following this.
But it seems this move has been telegraphed for a few days now.
