Department-Level Exercise (DLE) Series

Through this series, the Department of the Air Force is preparing to be a stronger, more lethal deterrent force, to provide an advantage against competitors and adversaries across all domains, and to ensure regional stability in the Indo-Pacific and beyond.

The DLE series will incorporate multiple command exercises into one overall threat deterrence scenario, including Resolute Force Pacific (REFORPAC), Resolute Space, Mobility Guardian, Emerald Warrior and Bamboo Eagle 25-3.

It will also integrate multiple allies and partners in specific component exercises with shared interests. Partner integration is critical to U.S. efforts to ensure regional and global peace and stability and provides a decisive advantage against complex threats.

The U.S. Explosive Ordnance Disposal (EOD) community celebrates its birthday on August 22, commemorating the graduation of the first Navy Mine Disposal class in 1941, which served as the foundation for all other U.S. military EOD programs.

The history of U.S. Army Explosive Ordnance Disposal (EOD) began during World War II in response to the threat of German delayed-action bombs and other enemy ordnance.

The first “Bomb Disposal” training school was established at Aberdeen Proving Ground, Maryland, in 1942 under the leadership of Maj. Thomas J. Kane, often referred to as the father of U.S. Army Bomb Disposal.

Following the war, some EOD units were deactivated or converted to reserve status and in 1949, the remaining units were redesignated as "Explosive Ordnance Disposal".

The Korean and Vietnam Wars highlighted the continued need for EOD capabilities and led to increased training and equipment investments.

EOD units have played a crucial role in recent conflicts, particularly in Afghanistan and Iraq, where they faced the challenge of Improvised Explosive Devices.

The emphasis on counter-IED efforts led to the establishment of the 52nd Ordnance Group (EOD), based in Fort Campbell, Kentucky, and the Fort Carson, Colorado-based 71st Ordnance Group (EOD).

Both groups are part of the 20th Chemical, Biological, Radiological, Nuclear, Explosives (CBRNE) Command, the U.S. military’s premier multifunctional and deployable CBRNE formation, located at Aberdeen Proving Ground, Maryland.

Soldiers and Army civilians from the 20th CBRNE Command deploy from 19 bases in 16 states to confront and defeat the world’s most dangerous hazards in support of joint, interagency and multinational operations.

EOD technicians continue to support Special Operations Forces and other military units in addition to Very Important Person Protection Support Activity missions, which provides protection to the president, first lady, vice president and foreign heads of states.

Happy birthday, EOD! More
