I caught this on vententersearch.com the other day and then was forwarded a link to additional info by LT Derek Franks (BTFD T375).  This door is pretty intense and, if not identified recognized on scene, could waste time and energy should we have to gain entry into a building.

Essentially, they are high security, reinforced steel doors with up to six (6) dead bolts (controlled by a single lock) and dressed to look like standard residential wooden doors.  Though it’s deceiving, shocking the door prior to attempting to force it should help you identify its construction as well as strong, and not-as-strong, points.

After seeing pictures and watching the video, it seems that either a K12 or solid through-the-lock techniques may be the best option if you find yourself up against this door.  Since all of the throws are controlled by one lock, pulling or spinning the lock and using key tools should be pretty quick.

Here are some links to info about the doors and to some tactics for forcible entry:
