The italian military is going to be the european administration to make the largest transition to Open Source software. During the next four years, more than 100.000 PCs will migrate to LibreOffice as part of LibreDifesa project, which will save 26 to 29 millon euros to italian administration.
The main reasons for the military to perform this move are interoperability and long-term accesibility of documents and information. The army of this country is standardising on the Open Document Format (ODF) and is advising its users to use free fonts.

In addition, they are considering the use of Linux for workstations and they are testing Zimbra for email, calendars, and collaboration suite.
