Who We Are
The United States Army Corps of Engineers (USACE) is made up of approximately 34,600 Civilian and 650 military members. Our military and civilian engineers, scientists and other specialists work hand in hand as leaders in engineering and environmental matters. Our diverse workforce of biologists, engineers, geologists, hydrologists, natural resource managers and other professionals meets the demands of changing times and requirements as a vital part of America's Army.
Our mission is to provide quality, responsive engineering services to the nation including:
- Planning, designing, building and operating water resources and other civil works projects (Navigation, Flood Control, Environmental Protection, Disaster Response, etc.)
- Designing and managing the construction of military facilities for the Army and Air Force. (Military Construction)
- Providing design and construction management support for other Defense and federal agencies. (Interagency and International Services)
Today, as always, we stand ready ... engineers, scientists, real estate specialists and administrators alike to meet national security, emergency and other national requirements.
How the Corps is Organized
The Chief of Engineers and Commander, USACE
The Chief of Engineers has separate and distinct command and staff responsibilities. As a staff officer at the Pentagon, the Chief advises the Army on engineering matters and serves as the Army's topographer and the proponent for real estate and other related engineering programs.
As commander of the US Army Corps of Engineers, the Chief of Engineers leads a major Army command that is the world's largest public engineering, design and construction management agency. His office defines policy and guidance and plans direction for the organizations within the Corps.

Divisions and Districts
The Corps is organized geographically into 8 divisions in the US and 41 subordinate districts throughout the US, Asia and Europe. The districts oversee project offices throughout the world. Divisions and districts are defined by watershed boundaries, not by states. In addition, a 9th provisional division with four districts was activated January 25, 2004, to oversee operations in Iraq and Afghanistan.
The Corps Laboratories
The Engineer Research and Development Center (ERDC) is the US Army Corps of Engineers research and development command. ERDC consists of eight unique laboratories.
Research support includes:
- Mapping and terrain analysis
- Infrastructure design, construction, operations and maintenance
- Structural engineering
- Cold regions and ice engineering
- Coastal and hydraulic engineering
- Environmental quality
- Geotechnical engineering
- High performance computing and information technology
