(a) the date their orders were issued; or
(b) 90 days before they report to active duty.
National Guard and Reserve members who qualify for the pre-activation benefit are covered as "active duty service members" and receive active duty medical and dental benefits.
Additionally, when National Guard or Reserve members qualify for pre-activation benefits, family members who are registered in the Defense Enrollment Eligibility Reporting System are also covered under TRICARE up to 90 days before the sponsor's active duty service begins. Family members become covered by TRICARE as "active duty family members during the pre-activation period and while the sponsor is activated.
The member's Service personnel office will tell members if they are eligible for pre-activation benefits when they receive their delayed-effective-date active duty orders.
