The Department of Defense (DoD) maintains one of the largest computer networks in the world, not the least through its famous DIY-sites. The network follows DoD personnel across the globe collecting, transferring and processing craft techniques, reports and manuals in forms as diverse as secret data warehouses, in-the-field mobile workshops and toolkits, and mission computers on board our undercover “craftmobiles”, for example for tracking insurgent crafters at Burning Man, Craft-ins and Etsy craft nights. The cyber terrain is constantly changing in size and shape as new missions are undertaken and new technology is deployed. As the DoD network is constantly shifting and threatened by cyber terror, such as spam and malicious amateur DIY activists posting rants on our forum. The new Cyber Craft Commando Unit (C3U) has since 2006 been protecting our frontiers against these threats.
