Avanti,
Slice is correct. I had five friends just get hired with Homeland Defense. 100% pilot job. If you a Helo guy, then you will fly helos for a while and then fixed-wing. If you are both, then you can fly both. Every location is different and some are a little more customs and some are a little more border patrol.
www.usajobs.gov has a posting for you to apply until April 14th. All of the new hires took about 4 months to get the call to get the "your hired." Hope this helps.
