TRICARE Fairness for National Guard and Reserve Retirees Act This bill provides that personnel of the Retired Reserve (comprising former National Guard and Reserve members) who are not yet age 60 but are receiving their retirement pay may purchase TRICARE health coverage for retired military personnel, rather than the presently allowed TRICARE Retired Reserve (which may have higher costs). The bill generally aligns the age for TRICARE health care benefits with the age at which retired National Guard and Reserve personnel begin receiving their retired pay. Under current law, Reserve Component personnel may retire below age 60, but not below 50, based on active duty performance.
