"Hate dialing up to DEFCON 1"

At first, I thought you were talking about DefCon, the convention, which really confused me.

Then, I realized you were talking about defense condition.

Agreed. I think it is pretty good overall, and can see potentially using it in my own projects. However, I don't think that the design of the technology class icons are particularly well execute. I feel like they suffer from an attempt to match the angles and styling of the logo too closely and would have rather seen more easily recognizable elements used to represent those concepts.
