Fact Sheet


Mil-OSS is a grass-roots organization that connects and empowers an active community of both civilian and military developers using, improving, and releasing Open Source Software (OSS) and hardware across the United States Department of Defense (DoD). Most members of Mil-OSS work with the DoD either directly or as contractors, and see their work in open source DoD projects as a patriotic support for our country’s Warfighters. OSS allows the DoD to improve software security, control development costs and increase innovation—all of which benefit the Warfighter.

Mission Statement
