Muster to test deployment capable numbers Published July 17, 2006 By Tech. Sgt. Rob Mims Air Reserve Personnel Center Public Affairs DENVER (AFPN) -- The Air Reserve Personnel Center conducts a muster for nearly 150 individual ready reservists July 20 and 27 at the Buckley Annex here to test the readiness of the force.The IRR Muster Program, mandated by U.S. law, exists to enhance readiness and ensure the Air Force can "reach out and touch" the IRR population when called upon to do so, said ARPC officials.Individual ready reservists are primarily Air Force members who have served on active duty but still have a military service obligation to the Air Force. "These musters provide the overall structure to gather and maintain IRR member contact and physical condition information, thereby increasing efficiency of the activation process for total or full mobilization," said Col. Ann Shippy, ARPC commander.In war and other times of crisis, it is sometimes necessary to call up IRR members. To ensure the call up works when needed, the Air Force holds a muster. Due to significant volunteerism, the Air Force Reserve has not had to mobilize the IRR since Desert Storm. Annually, IRRs report to an Air Force base usually within 150 miles of their residence. They receive a records review, basic medical screening and briefings. They are paid for their time in accordance with U.S. code.
