Individual Ready Reserve members who are not members of the National Guard or Selected Reserve (SELRES), are required to attend muster duty once per year. Members ordered to muster duty are required to perform a minimum of two hours of muster duty on the day of muster, as determined by the Secretary of the Military Department, and are entitled to earn Muster Duty Allowance (MDA) as compensation for completing muster duty. Muster duty is an annual screening to collect medical and personnel information from Ready Reservist members. Members who attend muster duty will receive access to helpful resources and benefits, and be provided with opportunities to mobilize.
The MDA is 125 percent of the average per diem rate in effect on September 30 of the calendar year preceding the calendar year in which the muster duty is performed.

Yes. The Secretaries of the Military Departments established procedures to ensure the continuous screening of the IRR. One of those screening tools is a muster.
