Well, thankfully we found some document to shed some light on it. I tell you, the IRR is a great deal. Once you finish up your active duty, you can pick and choose what you want to do and where you want to do your annual training. No weekend warrior stuff, and you don't have to be going with a whole unit (with all the assorted PITA stuff you have to do before deploying). You just pick up and leave. It's the military's greatest secret.
