What is known today as the Defense Ammunition Center (DAC) has changed its name several times since inception.

Before July 19, 1971, the U.S. Army Material Command Ammunition School (AMCAS), the U.S. Army Materiel Command Ammunition Center (AMCAC) (Advisor's Office, Civilian Career Office, Engineering Division, Storage and Out loading Division, and Evaluation Division) and the Programs and Control Office were elements of the Directorate for Special Missions, Savanna Army Depot (SAD), Savanna, IL.

On July 19, 1971, General Order #198 established the AMCAC as a separate activity reporting to the U.S. Army Materiel Command (AMC). The AMCAC now included all the elements of the Directorate for Special Missions.

On June 13, 1975, HQ AMC, by General Order #86, reassigned the AMCAC to the U.S. Army Armament Command (ARMCOM)

On January 7, 1977, by Permanent Order 1-3, AMCAC re-designated to U.S. Army Materiel Development and Readiness Command (DARCOM)

On January 17, 1979, by Permanent Order 4-1 DARCOM Ammunition Center re-designated to the U.S. Army Defense Ammunition Center and School (USADACS), to recognize its vital role in implementing the Army's new mission to manage conventional ammunition for the entire DOD

On September 30, 1987, Permeant Order 60-1 added the U.S. Army Technical Center of Explosives Safety (USATCES) as an element within USADACS.

In April 1993, the Demil Technology Office was added to USADACS to consolidate duties of the Joint Service Large Rocket Motor Demilitarization (JSLRMD) and Munitions Items Disposal Act System (MIDAS) offices in an effort to better manage the JSLRMD Technology R&D Program, the Army Conventional Ammunition Demil Technology R&D Program, and to develop; manage; and execute the MIDAS Program.

On December 5, 1996, USADACS re-designated to our current organizational name - the U.S. Army Defense Ammunition Center (DAC) by Permeant Order 340-1.

In July 1971, Mr. A.G. Ehringer was appointed the first Director of this activity and served in the capacity until his retirement in January 1979. Mr. John L. Byrd, Jr., was appointed to succeed Mr. Ehringer as the Director in January 1979. In 1987, the DAC was aligned under the U.S. Army Materiel Command’s Joint Munitions Command. Mr. Byrd continued in that capacity until his death on January 19, 1995.Mr. Larry V. Gulledge was appointed to the Director’s position from 9 June 1996 – 13 April 1997 and at the time was reassigned by Mr. Togo West as Senior Executive Service (SES) Civilian Deputy to the Commander, Industrial Operations Command (IOC). On 1 February 1998, Mr. James Q. Wheeler was appointed Director of DAC.

The DAC consisted of 26 elements and was the only entity within DOD that represented a variety of ammunition-oriented technical skills. Capability was enhanced by utilizing this variety of missions and specialties as a matrix organization. The DAC provides training, logistics

engineering, demil technology, explosive/chemical safety, technical assistance, and career management for the Quality Assurance Specialist (Ammunition Surveillance) (QASAS) and the Ammunition Management (AM) career programs to all DOD and other government agencies and was the only entity within DOD to perform design and safety testing of containers used for ground and shipboard transportation of ammunition.

In 2010, the Department of Defense Explosives Safety Board (DDESB) reduced emphasis on installation-level explosives safety reviews, focusing efforts instead on programmatic evaluation of the Services’ Explosives Safety Management Programs (ESMP). As a result, DA G-4 and DA Safety directed the DAC’s Logistics Review and Technical Assistance Office (LRTAO) to expand their mission to include performing Army Explosives Safety Surveys in conjunction AR 700-13 Worldwide Ammunition Logistics Reviews at headquarters, commands, installations, and other organizations having an ammunition-related mission.

In 2014, the DAC was realigned under the U.S. Army Training and Doctrine Command through the Chief of Ordnance, Combined Arms Support Command. Under this realignment the two DA career programs (CP20 and CP33), and demil technology directorate remained with the Joint Munitions Command as JMC South.
