These teams provide communications support to local public safety.

For instance, they may operate a truck with satellite uplink, computers, telephone and power generation at a staging area near a disaster so that the responders can communicate with the outside world.

There are also Mobile Air Transportable Telecommunications System ( MATTS ) assets which can be airlifted in.

Also portable Cellphone towers can be erected to allow local responders to access telephone systems.
