You qualify for a higher social security payment because of your military service, for active duty any time from 1940 through 2001 (the program was done away with in January 2002).
Up to $1200 per year of earnings credit (see below websites for more detail) credited at time of application - which can make a substantial difference in social security monthly payments upon your retirement.

You must bring your DD-214 to the Social Security Office - and you must ask for this benefit to receive it!
