The Selected Reserve (also called SELRES, SR, or mistakenly Selective Reserve) are the members of a U.S. military Ready Reserve unit that are enrolled in the Ready Reserve program and the reserve unit that they are attached to. Selected Reserve members and units are considered to be in an active status. When the term is applied to describing personnel, it is contrasted to the Full-time Reserve Unit Support (also called Full Time Support or FTS) members of the same reserve unit who are Active Duty. It is also contrasted to members of the Individual Ready Reserve who are not in active status.
