§ 3221. Army Reserve (a) Whenever the authorized strength of the Army Reserve is not prescribed by law, it shall be prescribed by the President. (b) Subject to the authorized strength of the Army Reserve, the authorized strength of the Army Reserve in members in each grade is that which the Secretary of the Army determines to be necessary to provide for mobilization requirements. The Secretary shall review these determinations at least once each year and revise them if he considers it necessary. However, no member of the Army Reserve may be reduced in his reserve grade, without his consent, as a result of such a determination.
