Offutt AFB, near Omaha, Nebraska, announced the same policy about six months ago when a new wing commander took the helm.
Security police/forces building and armory was in the area flooded out by the Missouri River and is unusable and slated for demolition. How many privately owned firearms stored there were damaged or ruined by the flooding?

Just recently happened at Tyndall.
