My guy, through his ham radio club, has been a volunteer at my state's emergency management center since 2010. He helped write the manual for the volunteer radio operators. He recently got an email saying that he needed a new ID badge because his security clearance had been upgraded. So we went and I waited out in the car while he got a new badge made with new picture ID. The emergency management is tied into homeland security.
I'm proud of him for many reasons, but the willingness to volunteer his own time to help his community is a big one.
