To amend title 10, United States Code, to prohibit the assignment of a member of the Armed Forces who is an only child to a combat-related military occupational specialty without the consent of the member.

Prohibits a member of the armed forces who is an only child from being assigned, without his or her written consent, to duty: (1) on a vessel or aircraft intended for, or likely to participate in, combat missions; or (2) in a combat-related occupational specialty. States that the written consent may be required as a condition of enlistment or appointment of an only child as a member of the armed forces. Provides that if a member becomes an only child after being assigned to such duties, the member: (1) may consent in writing to continue such duty; or (2) shall be reassigned upon request to noncombat duty as soon as practicable. Allows a member who requests such reassignment to be discharged or released from the armed forces at such time in lieu of such reassignment for the convenience of the Government in the discretion of the Secretary of the military department concerned.
