Must you be so critical of them? They have their hands tied by those in power and the chain of command.
No Indian or Pakistani would ever disrespect their armed forces like this, they'd be lynched.
They are not useless, they're rendered inert and unassuming by successive governments. Not to mention the fact that the army knows that if they intervene, sanctions will be slapped on Bangladesh and the economy will get hammered, there by making it all the more easier for our adversaries to take the country apart.
Simply bashing the military will not help, lets all stick to constructive criticism.
