37 U.S.C. § 301d — Multiyear retention bonus: medical officers of the armed forces

(a) Bonus authorized: (1) A medical officer described in subsection (b) who signs a written agreement to stay on active duty for two, three, or four years after finishing any other active-duty service commitment may, once the Secretary of the relevant military department accepts the agreement, be paid a retention bonus under this section. (2) The bonus cannot exceed $75,000 per year for a four-year agreement; the maximum yearly bonus for two-year and three-year agreements is reduced to reflect the shorter commitment. (b) Eligible officers: This section applies to an officer who (1) is an officer of the Medical Corps of the Army or Navy, or an Air Force officer designated as a medical officer; (2) is in a pay grade below O-7; (3) has at least eight years of creditable service, computed as described in section 302(g), or has finished any active-duty service commitment incurred for medical education and training; and (4) has completed initial residency training, or will complete it before September 30 of the fiscal year the officer signs the agreement. (c) Repayment: An officer who does not complete the agreed active-duty period must repay money under the repayment rules in section 303a(e).
