The day-to-day activities of the three mission areas are administered by a [[Lieutenant general (United States)|lieutenant general]] known as the [[List of United States Army Corps of Engineers Chiefs of Engineers|chief of engineers]]/commanding general. The chief of engineers commands the Engineer Regiment, comprising [[combat engineer]], rescue, construction, dive, and other specialty units, and answers directly to the [[Chief of Staff of the United States Army|Chief of Staff of the Army]]. Combat engineers, sometimes called [[sappers]], form an integral part of the Army's [[combined arms|combined arms team]] and are found in all Army service components: Regular Army, [[United States National Guard|National Guard]], and [[United States Army Reserve|Army Reserve]]. Their duties are to breach obstacles; construct fighting positions, fixed/floating bridges, and obstacles and defensive positions; place and detonate explosives; conduct route clearance operations; emplace and detect landmines; and fight as provisional infantry when required. For the military construction mission, the chief of engineers is directed and supervised by the Assistant Secretary of the Army for installations, environment, and energy, whom the President appoints and the Senate confirms. Military construction relates to construction on military bases and worldwide installations.
