Can you give examples? And do they also activiley participate in the upstream?

Most of what's used in enterprise are used, so no examples really needed. Upstream activity tends to be minimal, but it happens, usually indirectly via contractors. There are many stories online that can be found by searching, in regards to specific systems, and some software.

There are also various parties working hard to promote more OSS use in DoD, two examples: GAO, OSSI. Not to mention the DoD is mandated to release at least twenty percent of its own custom software as open source. Like anything gov, it's a slow process.

I guess department wise, DoD/Pentagon is leading the front in OSS.

Also, the requirement to release at least 20 percent of custom-developed code as OSS is not a sole DoD directive.

They are just enforcing the Federal Source Code Policy from: https://sourcecode.cio.gov/OSS/

The Tactical Service Oriented Architecture[1] has a Battle Command Display module that is built on top of Liferay[2]. There's other C2 systems that use Cesium[3]. I don't think the TSOA devs are pushing their code upstream, but that's just a guess.
