For officers who do not choose whether or not to stay in the Active Reserve, membership in the Standby Reserve is limited to one year, after which they must determine if they are transferring to the
Individual Ready Reserve, or to a drilling unit. The Standby Reserve is also used for personnel who have been designated key civilian employees, or who have a temporary hardship or disability. As such, they are not required to perform training and are not a part of units, but create a pool of trained individuals who could be mobilized if necessary as a last resort to fill manpower needs in specific skills. ==Organization==
