C. S. §§1521-22. • Service - To reach eligibility for a non-service-connected pension, a veteran must have one day or more of active duty in a "period of war", with at least 90 days total active duty. However, for a veteran who entered military service after 1980, the service requirement is simply to have completed a full period of active duty.
