Good parts of Brazil military.

I don't remember all details now, but the Air Force I am sure their official policy is that all their desktop machines run Ubuntu and all their server machines run Debian.

The Army and Navy don't have a broad policy like this, but also has lots of FOSS-related use and work.

Also Brazil government has several state companies that develop FOSS software, but several places still unfortunately rely too much on Microsoft (usually in the judiciary and executive branches)
