I thought it was cool to see another Linux adoption story, this time by the U.S. Army. One of the best quotes from this article:

“Red Hat 5 will link Linux with Microsoft and allow FCS forces to link with other brigade combat teams,” the Army official said. “This will be an interim solution because over the long haul, eventually all of the Army’s networks will be Linux-based.”

They plan eventually to have the whole thing running Linux.

Actually, Linux is being employed currently by all of the branches of the U.S. Military.
