Alabama State Defense Force The Alabama State Defense Force ( ASDF ) is a military entity authorized by the State Code of Alabama . The ASDF is the state ’ s authorized state defense force and assumes the state mission of the Alabama National Guard in the event the Guard is mobilized . The ASDF is composed of retired , prior active - duty , and prior - reserve military personnel and selected professional persons who volunteer their time and talents in further service to their state . The Alabama State Defense Force is allowed under section 31 - 2 - 8 of the Code of Alabama . History . Prior to the modern National Guard , states would provide volunteer militia units to augment the federal army in times of war . In the Mexican - American War , Alabama provided the United States with multiple units of Alabama militia , with most serving for less than a year . During the American Civil War , both Union units and Confederate units were raised in support of the war effort . In the Spanish - American War , Alabama raised three volunteer infantry units . After the declaration of World War II , the majority of the National Guard was mobilized , leaving governors without troops to guard against invasion , provide disaster relief , and protect against civil unrest . Therefore , many states , including Alabama , raised state defense force s to act as a replacement for the National Guard during the war . In 1940 , Governor Frank M . Dixon created the Alabama State Guard , recruiting primarily from World War I veterans , mainly from the American Legion . Alabama took a unique approach in creating its state defense force . While other states actively recruited from veteran ' s organizations , Alabama went a step further and " gave the American Legion of Alabama the responsibility for creating and running its State Guard , " and in return , Alabama " was able to achieve a functioning state guard sooner than most states . " By using an existing private organization as the framework for their state defense force , Alabama was able to achieve full readiness far sooner than might be expected . At the war ' s end , the Alabama State Guard was deactivated . On December 22 , 1983 , Governor George Wallace signed Executive Order Number 20 , which authorized the creation of the Alabama State Defense Force , the successor of the Alabama State Guard which was disbanded in World War II . On August 14 , 2012 , Governor Robert Bentley signed into law the Alabama State Defense Force bill ( SB278 ) , which added clarification to the role of the ASDF in relation to the Alabama National Guard , so that the two organizations can be better integrated in future stateside missions . Duties . The purpose of the Alabama State Defense Force is to augment or replace the stateside Alabama National Guard when some or all of these National Guard units have been deployed outside of the state . The ASDF is responsible for the non - combat state mission of the National Guard . The ASDF specifically lists its primary responsibilities as such : All four brigades of the ASDF activated personnel during Hurricane Katrina . Composed of some 600 activated members , the ASDF units which were activated assisted in operating shelters , distribution stations and warehousing as a part of the relief effort to victims of the storm .
