I don't often plug a commercial source - but this one is worth having just for the questions on health care alone...
The Retired Military Personnel Handbook, now in its eighth year of publication, is specifically written for all military personnel, retirees and their families, and explains all aspects of retirement benefits and how to get them.
Topics include TRICARE Plus program A, the Federal LTC Insurance program, tax policies affecting retirement accounts, estate tax treatment and long-term care premiums, and new retirement lifestyle information, including how to evaluate continuing-care communities and nursing homes and many others.
The 2008 edition has the latest information on military retirement and is a good reference guide for those nearing retirement or already retired. The handbook still costs $10.95, plus shipping and handling, and is available for single or bulk orders at www.fedweek.com/pubs/index.php, or call the 24-hour toll-free order line at (888) 333-9335, or mail your order with payment (total $15.70) to: FEDweek, PO Box 5519, Glen Allen, VA 23058.
