What term describes members who leave active service before their contract ends and do not perform drill periods?

The term that accurately describes members who leave active service before their contract ends and do not perform drill periods is the Individual Ready Reserve. This category includes individuals who have completed their active duty service and are not currently in an active status but remain part of the reserve forces. They are not required to participate in drills or training, differentiating them from other reserve components who have ongoing obligations.

Traditional Reservists, on the other hand, are actively involved in unit drills and training. Members of the Active Guard Reserve are full-time servicemembers who perform duties similar to active duty personnel, while Drill Status Guardsmen are part of the National Guard and typically participate in regular drill activities, which is not applicable to those who have left active service before their contract ended. Thus, the Individual Ready Reserve accurately encapsulates the status of such members.
