In a rather "interesting" comparison, the author of this paper in IEEE Spectrum, speculates that the tactics used by insurgents in Iraq are similar to the ones used by the Open Source movement, and that the difficulties that the coalition forces are facing are similar to the challenges that monolithic companies like Microsoft are encountering for competing with a more creative and flexible opponent.

On the bright side, the author concludes the paper stating that adopting an "Open Source"-approach to warfare (such as Agile development mentality) may be an appropriate response.
