1) Install "Common Access Card Viewer" from "CD 3"
2) Control Click (or Right Click) on the "Common Access Card Viewer" Application in your "Utilities" Folder
3) Select "Show Package Contents"
4) Navigate to "Resources"
5) Have Fun!
The only way to actually use them is to have the Card reader and a DoD CAC and to have your sys admin configure OSX to use that for login instead of standard Username and password.
