An indication of the United States' close operational cooperation with Canada is the creation of a new message distribution label within the main US military communications network. Previously, the marking of NOFORN (i.e., no foreign nationals) required the originator to specify which, if any, non-US countries could receive the information. A new handling caveat, USA/AUS/CAN/GBR/NZL eyes only, used primarily on intelligence messages, gives an easier way to indicate that the material can be shared with the Five Eyes members.[19]
