Retiree activities offices are made up of volunteers from all services and includes surviving spouses. Their charter is to coordinate, establish and staff an office on an active-duty, reserve or guard base through command channels that will assist retirees with myriad actions. These actions include: serving as an information center for space-available travel, TRICARE, base services, etc; offering referrals for financial-assistance and pay matters; counseling active-duty Airmen nearing retirement; and providing literature on retirement issues. Another major activity involves working with base agencies to set up Retiree Appreciation Day events offering flu shots by base medical personnel, briefings by different base agencies on respective services, tax preparation and advice, staff judge advocate assistance, base tours, etc.
