I got recalled in 2001, right after 9/11. I was already an individual reservist assigned to USSOCCENT so I knew it was coming. They called me on a friday after lunch and faxed orders to my local bank for me to pick up, they told me to report by Monday to Tampa. All the airports were pretty much closed and I had to drive the whole way so I left about 3am the next morning. It was pretty chaotic back then, no screening, etc. Just report with your uniforms, all your military records, including medical if you have them. You should also have your power of attorney, etc all ready to go. I took all my DCUs (had always been the SOCCENT UOD)and combat gear I had been issued and one set of Class A's(which I never wore). I also took my privately owned 45 and my own BUIS that I preferred. I'd pack well, if you forget anything you will probably have to buy it there, when I was recalled they would not allow recalled reservists to take leave-that may have changed now.
