About U.S. Army Corps of Engineers (Wikipedia Record):

The United States Army Corps of Engineers (USACE) is the military engineering branch of the United States Army. A Direct Reporting Unit (DRU), it has three primary mission areas: Engineer Regiment, military construction, and civil works. USACE has 37,000 civilian and military personnel, making it one of the world's largest public engineering, design, and construction management agencies. The USACE workforce is approximately 97% civilian and 3% active duty military. The civilian workforce is mainly located in the United States, Europe, and in select Middle East office locations. Civilians do not function as active duty military and are not required to be in active war and combat zones; however, volunteer opportunities do exist for civilians to do so.
