WORDS FROM THE COMMANDER
The Joint Services Detachment (JSD) is a State Defense Force military unit and is part of the organized militia of the State of South Carolina. It was organized in 1996 by South Carolina Adjutant General Stanhope S. Spears.
The JSD’s present table of organization calls for 18 uniformed members, 12 associate members, plus such advisors as the Adjutant General may designate. JSD’s mission is to provide professional expertise and support for projects which materially benefit current military activities of the South Carolina Military Department (SCMD), and/or which promote the professional military image, historical stature, and reputation for reliability and achievement, of the SCMD.
The JSD operates similarly to a civil affairs detachment. The 30 plus “citizen-soldier” members are comprised of academic, governmental and business leaders, and members of the military, medical, legal and financial professions. All JSD members are volunteers, all are proud of their service, and all are proud of the military uniform they wear. In short, the JSD is an organization where initiative, teamwork, leadership and expertise are bound together at many levels and across many disciplines, so to assist the SCMD assist and protect the citizens of South Carolina, and at no appropriated cost to the taxpayer.
