DHS = Department of Homeland Security
Thanks, Ron, but I knew that. My point is that the DHS is composed of several specific services like the Coast Guard, TSA, US Secret Service, etc. A total of 240,000 people work in these areas. If you enlist in the military, you don’t just join the Department of Defense. You join the Army, Navy, Marines, or Air Force. So who do these pseudo military types riding around in the scary black trucks actually work for? TSA? ICE? BSA (Barry’s Secret Army)?
Here is the DHS organizational chart: http://www.dhs.gov/xlibrary/assets/dhs-orgchart.pdf
What is your guess?
