DD Form 2656 is a Department of Defense form used by members of the uniformed services to designate beneficiaries for certain benefits after their death. The purpose of the form is to establish who will receive benefits such as Survivor Benefit Plan (SBP) annuity, unpaid pay and allowances, and any other benefits the member may have elected. The form is used to provide instructions and preferences for the distribution of these benefits. The 2009-2019 version of the form likely refers to the years it was in use, indicating any updates or revisions made during that period.
