Individual Ready Reserve (IRR) members who are not in the National Guard or Selected Reserve (SELRES) are required to serve muster duty once per year.
IRR members are required to perform at least two hours of muster duty the day of muster, as determined by their service branch. Participants are entitled to receive muster duty allowance (MDA) for muster duty completion.
Muster duty is an annual screening to collect medical and personnel information from IRR members, who are provided with mobilization opportunities while also receiving access to resources and benefits.
The MDA is 125% of the average per diem rate in effect September 30 of the calendar year preceding the calendar year when the muster duty is done, according to the Defense Finance and Accounting Service.

It may be an in-person muster (readiness and personnel accountability muster) or a virtual muster (VM).
