Title 10 › Subtitle Subtitle E— - Reserve Components › Part PART II— - PERSONNEL GENERALLY › Chapter CHAPTER 1205— - APPOINTMENT OF RESERVE OFFICERS › § 12201

Last updated Apr 6, 2026|Official source

Summary

People appointed as reserve officers must be given a reserve rank that matches a rank used in the regular force and must take the required federal oath. To be an officer in the Army National Guard of the United States or the Air National Guard of the United States, a person must first be appointed to and federally recognized in the same rank in the Army National Guard or Air National Guard. If an officer moves from active duty to a reserve active-status list under rules set by the Secretary of Defense, they do not have to take the oath again to qualify. The Secretary in charge of each service must set the physical, mental, moral, professional, and age rules for reserve appointments. No one can be appointed unless they are at least 18 years old and either a U.S. citizen, a lawful permanent resident, or have prior service in the armed forces or the National Security Training Corps. A person with a physical defect can be appointed if the Secretary decides it will not stop them from doing the job. For health specialties declared critically needed in wartime, the Secretary cannot set an initial appointment maximum age below 47.

(a)(1)To become an officer of a reserve component a person must be appointed as a Reserve of an armed force in a grade corresponding to a grade authorized for the regular component of the armed force concerned and, except as provided in paragraph (2), subscribe to the oath prescribed by section 3331 of title 5. In addition, to become an officer of the Army National Guard of the United States or the Air National Guard of the United States, he must first be appointed to, and be federally recognized in, the same grade in the Army National Guard or the Air National Guard, as the case may be.
(2)If an officer is transferred from the active-duty list of an armed force to a reserve active-status list of an armed force in accordance with regulations prescribed by the Secretary of Defense, the officer is not required to subscribe to the oath referred to in paragraph (1) in order to qualify for an appointment under that paragraph.
(b)Except as otherwise provided by law, the Secretary concerned shall prescribe physical, mental, moral, professional, and age qualifications for the appointment of persons as Reserves of the armed forces under his jurisdiction. However, no person may be appointed as a Reserve unless he is at least 18 years of age and—
(1)he is a citizen of the United States or has been lawfully admitted to the United States for permanent residence under the Immigration and Nationality Act (8 U.S.C. 1101 et seq.); or
(2)he has previously served in the armed forces or in the National Security Training Corps.
(c)A person who is otherwise qualified, but who has a physical defect that the Secretary concerned determines will not interfere with the performance of the duties to which that person may be assigned, may be appointed as a Reserve of any armed force under the jurisdiction of that Secretary.
(d)In prescribing age qualifications under subsection (b) for the appointment of persons as Reserves of the armed forces under his jurisdiction, the Secretary concerned may not prescribe a maximum age qualification of less than 47 years of age for the initial appointment of a person as a Reserve to serve in a health profession specialty which has been designated by the Secretary concerned as a specialty critically needed in wartime.
