You can get both Social Security benefits and military retirement. Generally, there is no offset of Social Security benefits because of your military retirement. You will get your full Social Security benefits based on your earnings. However, your Social Security benefit may be reduced if you also receive a government pension based on a job in which you did not pay Social Security taxes.

More information may be found in the Social Security Administration’s fact sheet called "Military Service and Social Security," publication number 05-10017, which is available on the Internet.  You can file for retirement benefits online.
