BD has an army because of Pak, who recruited Bengali folks into the army only to find they revolted and mutinied in collusion with India!!! And, East Bengal regiments were formed - the blunder of the highest order!!! As if it were not enough, they were deployed in the East Pak!!! The Pak High Command's stupidity had no limits!!! By the by, the Indian Army, following the British Indian tradition, has no Bengal regiments but has tons of Gurkha regiments....
Now, BD has no enemy!!! And, her army is for ceremonial purposes only!!! Even if the Burmese Army marches up to their capital city no BD folk would fire a single shot even with an air gun just to protest!!! Nor do they care!!! And, this is per design since no ex Pak Ordu members, fluent in Urdu/Pashtun/Baloch etc. and trained into a war machine by Punjabi/Pashtun NCO/JCOs are any longer there....
Pak has had her revenge by HIS PERMISSION...
