Army did a fascinating job (specially with the civilians stuck in the building).
However I have a question in regards to how we approach these dens to the people here who has more knowledge about defense.
In the west, they usually have armed police, once they have suspicion or is confirmed about a position of a suspected criminals, they would silently enter the building, barge into the apartment and arrest or shoot the criminals before they can get ready. What stops us from using that tactics in Bangladesh? Why do we announce it with a mic and let them prepare for hours?
