aaronsdaddy is not really correct. In any 740 day period, any day a Guardsman/Reservist spends deployed (whether overseas or in the States) is called a "high tempo day". If you accumulate more than 400 "high tempo days" you become effectively non-deployable. If a deployment will take you over 400 "high tempo days" in the middle of the deployment, you greatly lessen your chances of being deployed.\n\nIt is still technically possible to be deployed with more than 400 high tempo days, but the general grade officers that be have to jump through so many hoops they have decided it is just easier to activate someone else who has the high tempo days available to rack up.\n\nIf you are a Reservist and you want to volunteer, just talk to your personnel sergeant. I guarantee you that he will hook you up. And if you want to go, let them know. Maybe someone else who doesn't want to go will owe you a kegger when you get back.
