(1) may be placed on the reserve active-status list of that armed force in the grade equivalent to the permanent regular or reserve grade, and in the same competitive category, in which the person previously served satisfactorily on active duty or in an active status; and
(2) may be credited for the purpose of determining date of rank under section 741 (d) of this title with service in grade equal to that held by that person when discharged or separated.

10 USC 12207 - Commissioned officers: service credit upon original appointment

(a) 
(1) For the purpose of determining the grade and the rank within grade of a person receiving an original appointment as a reserve commissioned officer (other than a commissioned warrant officer) in the Army, Navy, Air Force, or Marine Corps, the person shall be credited at the time of the appointment with any commissioned service (other than service as a commissioned warrant officer) performed before such appointment as a regular officer, or as a reserve officer in an active status, in any armed force, the National Oceanic and Atmospheric Administration, or the Public Health Service.
(2) The Secretary of Defense shall prescribe regulations, which shall apply uniformly among the Army, Navy, Air Force, and Marine Corps, to authorize the Secretary of the military department concerned to limit the amount of prior commissioned service with which a person receiving an original appointment may be credited under paragraph (1), or to deny any such credit, in the case of a person who at the time of such appointment is credited with constructive service under subsection (b).
(b) 
(1) Under regulations prescribed by the Secretary of Defense, a person who is receiving an original appointment as a reserve commissioned officer (other than a commissioned warrant officer) of the Army, Navy, Air Force, or Marine Corps, or a designation in, or an assignment to, an officer category in which advanced education or training is required and who has advanced education or training, shall be credited with constructive service for such education, training, or experience, as follows:
(A) One year for each year of advanced education beyond the baccalaureate degree level, for persons appointed or designated in, or assigned to, officer categories requiring such advanced education or an advanced degree as a prerequisite for such appointment, designation, or assignment. In determining the number of years of constructive service to be credited under this subparagraph to officers in any professional field, the Secretary concerned shall credit an officer with, but with not more than, the number of years of advanced education required by a majority of institutions that award degrees in that professional field for completion of the advanced education or award of the advanced degree.
(B) 
(i) Credit for any period of advanced education in a health profession (other than medicine and dentistry) beyond the baccalaureate degree level which exceeds the basic education criteria for such appointment, designation, or assignment, if such advanced education will be directly used by the armed force concerned.
(ii) Credit for experience in a health profession (other than medicine or dentistry), if such experience will be directly used by the armed force concerned.
(C) Additional credit of
(i)  not more than one year for internship or equivalent graduate medical, dental, or other formal health professional training required by the armed forces, and
(ii)  not more than one year for each additional year of such graduate-level training or experience creditable toward certification in a speciality required by the armed force concerned.
(D) Additional credit, in unusual cases, based on special experience in a particular field.
(E) Additional credit for experience as a physician or dentist, if appointed, assigned, or designated as a medical or dental officer.

(A) If the Secretary of Defense determines that the number of officers in a health profession described in subparagraph (B) who are serving in an active status in a reserve component of the Army, Navy, or Air Force in grades below major or lieutenant commander is critically below the number needed in such health profession by such reserve component in such grades, the Secretary of Defense may authorize the Secretary of the military department concerned to credit any person who is receiving an original appointment as an officer for service in such health profession with a period of constructive credit in such amount (in addition to any amount credited such person under paragraph (1)) as will result in the grade of such person being that of captain or, in the case of the Navy Reserve, lieutenant.
(B) The types of health professions referred to in subparagraph (A) include the following:
(i) Any health profession performed by officers in the Medical Corps of the Army or the Navy or by officers of the Air Force designated as a medical officer.
(ii) Any health profession performed by officers in the Dental Corps of the Army or the Navy or by officers of the Air Force designated as a dental officer.

(4) Constructive service credited an officer under this subsection is in addition to any service credited that officer under subsection (a) and shall be credited at the time of the original appointment of the officer or assignment to or designation in an officer category in which advanced education or training or special experience is required.
(c) Constructive service may not be credited under subsection (b) for education, training, or experience obtained while serving as a commissioned officer (other than a warrant officer) on active duty or in an active status. However, in the case of an officer who completes advanced education or receives an advanced degree while on active duty or in an active status and in less than the number of years normally required to complete such advanced education or receive such advanced degree, constructive service may, subject to regulations prescribed under subsection (a)(2), be credited to the officer under subsection (b)(1)(A) to the extent that the number of years normally required to complete such advanced education or receive such advanced degree exceeds the actual number of years in which such advanced education or degree is obtained by the officer.
(d) If the Secretary of Defense determines that the number of qualified judge advocates serving on the active-duty list of the Army, Navy, Air Force, or Marine Corps in grades below lieutenant commander or major is critically below the number needed by that armed force in those grades, the Secretary of Defense may authorize the Secretary of the military department concerned to credit any person who is receiving an original appointment with a view to assignment to the Judge Advocate Generals Corps of the Army or appointment to the Judge Advocate Generals Corps of the Navy, or who is receiving an original appointment in the Air Force or Marine Corps with a view to designation as a judge advocate, with a period of constructive service in such an amount (in addition to any amount credited such person under subsection (b)) as will result in the grade of such person being that of captain or, in the case of the Navy, lieutenant, and the date of rank of such person being junior to that of all other officers of the same grade serving on the active-duty list.
(e) Constructive service credited an officer under subsection (b) or (d) shall be used only for determining the officers
(1) initial grade as a reserve officer;
(2) rank in grade; and
(3) service in grade for promotion eligibility.
(f) The grade and position on the reserve active-status list of a person receiving an appointment as a reserve officer who at the time of appointment is credited with service under this section shall be determined under regulations prescribed by the Secretary of Defense based upon the amount of service credited.

If at the time of any such valuation the Board of Actuaries determines that there has been an actuarial gain or loss to the Fund as a result of changes in actuarial assumptions since the last valuation or as a result of any differences, between actual and expected experience since the last valuation, the Board shall recommend to the Secretary a premium rate schedule for the amortization of the cumulative gain or loss to the Fund resulting from such changes in assumptions and any previous such changes in assumptions or from the differences in actual and expected experience, respectively, through an increase or decrease in the payments that would otherwise be made to the Fund.
