It wasn't because of 9/11. It wasn't because I had a tradition of military service in my family. And while the pay and benefits are nice, it wasn't for those reasons, either. That wasn't why I joined the U.S. Air Force Reserves in 2003 and later switched to the Air National Guard. I joined for the same reason I became a rabbi: I have a desire to serve others and be part of something larger than myself.
