Defines who counts as an “eligible person” under 38 U.S.C. 4103A by adding a clear, statutory definition: (1) a spouse already described in 38 U.S.C. 4101(5), and (2) the spouse of any person who died while a member of the Armed Forces. The change clarifies eligibility for the benefit or authority tied to that statutory provision so that surviving spouses of service members who died on active duty are explicitly included.
