The Sensitive Compartmented Information Facility is a tent designed to keep communications secure when the President is out and about.
Designed to withstand eavesdropping, phone tapping and computer hacking, Sensitive Compartmented Information Facilities — also known as SCIFs — are protected areas where classified conversations can be held.
They can be permanent enclosures within a building, or mobile areas set up when a world leader is on the move, to allow them to view sensitive documents or have secret conversations without any outsiders listening or hacking in.
