What fight scene with in a movie made no sense?

Whether a battle or two people going out of tooth and nail, which fight sequence just defies logic even with in the movie itself.

For me it is the cops vs Bane's mercenary army. Cops had batons and maybe some body armor. The mercs had light tanks and automatics which failed to kill the first dozen or so cops. When during the flight, Bane even takes to punching a few policemen who get to close yet next to him is a mercenary with a gun who doesn't use it.

To say they were low on ammo doesn't work. They could have demanded munitions from the army for a guarantee that they wouldn't donate the bomb.
