The United States Army Corps of Engineers (USACE) is both a direct reporting unit (DRU) and the military engineering branch of the United States Army that 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, 3% active duty military. The civilian workforce is primarily 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.
Military engineering is loosely defined as the art, science, and practice of designing and building military works and maintaining lines of military transport and military communications. Military engineers are also responsible for logistics behind military tactics. Modern military engineering differs from civil engineering. In the 20th and 21st centuries, military engineering also includes CBRN defense and other engineering disciplines such as mechanical and electrical engineering techniques.
Corps is a term used for several different kinds of organization. A military innovation by Napoleon I, the formation was first named as such in 1805. The size of a corps varies greatly, but two to five divisions and anywhere from 40,000 to 80,000 are the numbers stated by the US Department of Defense.
A sapper, also called a combat engineer, is a combatant or soldier who performs a variety of military engineering duties, such as breaching fortifications, demolitions, bridge-building, laying or clearing minefields, preparing field defenses, and road and airfield construction and repair.
The Corps of Royal Engineers, usually called the Royal Engineers (RE), and commonly known as the Sappers, is the engineering arm of the British Army. It provides military engineering and other technical support to the British Armed Forces and is headed by the Chief Royal Engineer. The Corps Headquarters and the Royal School of Military Engineering are in Chatham in Kent, England. The corps is divided into several regiments, barracked at various places in the United Kingdom and around the world.
A combat engineer is a type of soldier who performs military engineering tasks in support of land forces combat operations. Combat engineers perform a variety of military engineering, tunnel and mine warfare tasks, as well as construction and demolition duties in and out of combat zones.
William C. Gribble Jr. graduated from the United States Military Academy in 1941 and was commissioned in the Corps of Engineers.
A rifleman is an infantry soldier armed with a rifled long gun. Although the rifleman role had its origin with 16th century hand cannoneers and 17th century musketeers, the term originated in the 18th century with the introduction of the rifled musket. By the mid-19th century, entire regiments of riflemen were formed and became the mainstay of all standard infantry, and rifleman became a generic term for any common infantryman.
The Canadian Military Engineers is the military engineering personnel branch of the Canadian Armed Forces. The members of the branch that wear army uniform comprise the Corps of Royal Canadian Engineers.
In the United States Army, the term combat support refers to units that provide fire support and operational assistance to combat elements. Combat support units provide specialized support functions to combat units in the following areas
The Royal Australian Engineers (RAE) is the military engineering corps of the Australian Army. The RAE is ranked fourth in seniority of the corps of the Australian Army, behind the Staff Cadets, Armoured and Artillery Corps. The corps was formed by the amalgamation of the various colonial engineer corps of the states and territories of Australia in 1902 and since then has served in various conflicts including World War I, World War II and the Vietnam War. The corps has also served on numerous peacekeeping operations and was heavily involved in the Australian contribution to the war in Afghanistan.
The Corp of Sri Lanka Engineers (SLE) is a combat support arm of the Sri Lanka Army which provides military engineering. It is made up of ten regular regiments and one volunteer regiment. Headquartered at Panagoda Cantonment, it is headed by the Centre Commandant.
The Indian Army Corps of Engineers is a combat support arm which provides combat engineering support, develops infrastructure for armed forces and other defence organisations and maintains connectivity along the borders, besides helping the civil authorities during natural disasters. College of Military Engineering, Pune (CME) is the premier technical and tactical training institution of the Indian Army Corps of Engineers.
Several military services have combat engineer service corps:
A pioneer is a soldier employed to perform engineering and construction tasks. The term is in principle similar to sapper or combat engineer.
College of Military EngineeringPune (CME) is a technical and tactical engineering training institution of the Indian Army Corps of Engineers of the Indian Army. Training of Combat Engineers, Military Engineering Service, Border Roads Engineering Services (BRES) and Survey is done here.
The United States first formed a military engineering capability on 16 June 1775, when the Continental Congress established an army with a chief engineer and two assistants. Subsequently, on 16 March 1802, the Corps of Engineers was organized by the President. Today, Military Engineers are grouped separately within each of the armed services.

The Indonesian Army Corps of Engineers, abbreviated Pusziad, or simply Zeni is an Indonesian Army Central Executive Agency made up of some 15,000 civilian and military personnel, making it one of Southeast Asia's and the ASEAN's, largest public engineering, design, and construction management agencies. The Corps is involved in a wide range of disaster relief and public works projects within the republic, as well as in combat support operations. The Indonesian term for military engineers, Zeni, is derived from the Dutch genie, meaning sapper.
