The Command and Tactical Supports Unit of the Brigade ensures the functioning of the Great Unit Command in terms of logistics and communication.
It is constituted by a company command and a signals command. With volunteer personnel, it is located in Sassari.
It originated from the "Sassari" Command and Signals Unit constituted on 30th July 1991 for the "Sassari" Motorized Brigade. With the inclusion of the "Sassari" Sappers Engineer Company, on 1st April 1993 it was renamed Command and Tactical Supports Unit.
The Company was later substituted by the 5th Sappers Engineer Regiment.
