The closest links of the U.S. IC to other foreign intelligence agencies are to Anglophone countries: Australia, Canada, New Zealand, and the United Kingdom. There is a special communications marking that signals that intelligence-related messages can be shared with these four countries. An indication of the United States' close operational cooperation is the creation of a new message distribution label within the main U.S. military communications network. Previously, the marking of NOFORN (i.e., No Foreign Nationals) required the originator to specify which, if any, non-U.S. countries could receive the information. A new handling caveat, USA/AUS/CAN/GBR/NZL Five Eyes, used primarily on intelligence messages, gives an easier way to indicate that the material can be shared with Australia, Canada, United Kingdom, and New Zealand.
