For much of the final decades of the twentieth century, National Guard personnel typically served "One weekend a month, two weeks a year", with a portion working for the Guard in a full-time capacity as either Active Guard and Reserve (AGR), Army Reserve Technicians or Air Reserve Technicians (ART). This changed dramatically during the 1990-91 Gulf War, and continued on to present day, with both the Federal Reserve Components and the National Guard increasingly utilized as an "operational" force for worldwide deployment.
