To amend title 10, United States Code, to include certain prior active duty as a regular member of an Armed Force for reduced eligibility age for retirement as a member of the reserve components.

This bill amends federal law to allow certain prior active duty service as a regular member of an Armed Force to count toward the reduced eligibility age for retirement in the reserve components. The change directly affects members of the Ready Reserve who have served on active duty, enabling them to qualify for retirement benefits at an earlier age than previously permitted under current rules. The legislation applies retroactively to qualifying service performed after January 28, 2008, ensuring that past service is recognized for these retirement calculations.
