Broke a door.

[Alley]

When a door has icon that it can be broke, how exactly to broke it. Only with explosion? Can I use my hand like with walls?

[Vassago Rain]

Any kind of damage. AP ammo is the most effective way to destroy doors, cars, and other stuff. No, there's no aug for 'break down the door,' but all the ones that do damage can destroy them in really short order, since they're all armor piercing or explosive to a lesser or greater degree.
