United States Org Chart for MilGov and CivGov?

[agrikk]

Has anyone ever gathered, organized and fleshed out the organizational structure for MilGov and CivGov?

I'm resurrecting a campaign that I ran a few years ago and will take the surviving character and new characters though the US modules.

I'd like to have the organizations fleshed out a bit to give flavor to how decimated both groups are.
