In military science, engineering refers to the practice of designing, building, maintaining and dismantling military works, including offensive, defensive and logistical structures, to shape the physical operating environment in war. It most often deals with fortifications and earthworks, the laying and clearing minefields, and the construction and destruction of bridges.

According to NATO, "Military Engineering is that engineer activity undertaken, regardless of component or service, to shape the physical operating environment.' Military Engineering incorporates support to manoeuvre and to the force as a whole, including military engineering functions such as engineer support to Force Protection, Counter - Improvised Explosive Devices, Environmental Protection, Engineer Intelligence and Military Search. Military Engineering does not encompass the activities undertaken by those 'engineers' who maintain, repair and operate vehicles, vessels, aircraft, weapon systems and equipment." ^[1]

Military engineering is an important academic subject taught in military academies. The construction and demolition tasks related to military engineering are usually performed by military engineers including soldiers trained as sappers or pioneers.^[2] In modern armies, soldiers trained to perform such tasks while well forward in battle and under fire are often called combat engineers.

In some countries, military engineers may also perform non-military construction tasks in peacetime such as flood control and river navigation works, but such activities do not fall within the scope of military engineering.

Origins[link]

The word engineer was initially used in the context of warfare, dating back to 1325 when engine’er (literally, one who operates an engine) referred to "a constructor of military engines".^[3] In this context, "engine" referred to a military machine, i. e., a mechanical contraption used in war (for example, a catapult).

As the design of civilian structures such as bridges and buildings matured as a technical discipline, the term civil engineering^[4] entered the lexicon as a way to distinguish between those specializing in the construction of such non-military projects and those involved in the older discipline. As the prevalence of civil engineering outstripped engineering in a military context and the number of disciplines expanded, the original military meaning of the word “engineering” is now largely obsolete. In its place, the term "military engineering" has come to be used.

History[link]

Perhaps the first civilization to have a dedicated force of military engineering specialists were the Romans, whose army contained a dedicated corps of military engineers known as Roman military engineering.This group was pre-eminent amongst its contemporarie. The scale of certain military engineering feats, such as the construction of a double-wall of fortifications 30 miles (48 km) long, in total (both walls combined total), in just six weeks to completely encircle the besieged city of Alesia in 52 B.C.E., is just one example. Such military engineering feats would have been completely new, and probably bewildering and demoralizing, to the Gallic defenders. The best known of these Roman army engineers due to his writings surviving is Vitruvius.

In ancient times, military engineers were responsible for siege warfare and building field fortifications, temporary camps and roads. The most notable engineers of ancient times were the Romans and Chinese, who constructed huge siege-machines (catapults, battering rams and siege towers) and were responsible for constructing fortified wooden camps and paved roads for their legions. Many of these Roman roads are still in use today.

For 500 years after the fall of the Roman empire, the practice of military engineering barely evolved in the west. In fact, much of the classic techniques and practices of Roman military engineering was lost. Through this period, the foot soldier (who was pivotal to much of the Roman military engineering capabiltiy) was largely replaced by mounted soldiers. It was not until later in the Middle Ages military engineering saw a revival focused on siege warfare. ^[5]

Military engineers planned castles and fortresses. When laying siege, they planned and oversaw efforts to penetrate castle defences. When castles served a military purpose, one of the tasks of the sappers was to weaken the bases of walls to enable them to be breached before means of thwarting these activities were devised. Broadly speaking, sappers were experts at demolishing or otherwise overcoming or bypassing fortification systems.

With the 14th century development of gunpowder, new siege engines in the form of cannons appeared. Initially military engineers were responsible for maintaining and operating these new weapons just as had been the case with previous siege engines. In England, the challenge of managing the new technology resulted in the creation of the Office of Ordnance around 1370 in order to administer the cannons, armaments and castles of the kingdom. Both military engineers and artillery formed the body of this organization and served together until the office's predecessor, the Board of Ordnance was disbanded in 1855.^[6]

In comparison to older weapons, the cannon was significantly more effective against traditional medieval fortifications. Military engineering significantly revised the way fortifications were built in order to be better protected from enemy direct and plunging shot. The new fortifications were also intended to increase the ability of defenders to bring fire onto attacking enemies. Fort construction proliferated in 16th century Europe based on the trace italienne design.^[7]

By the 18th century, regiments of foot (infantry) in the British, French, Prussian and other armies included pioneer detachments. In peacetime these specialists constituted the regimental tradesmen, constructing and repairing buildings, transport wagons, etc. On active service they moved at the head of marching columns with axes, shovels and pickaxes clearing obstacles or building bridges to open the way for the bulk of the regiment to move through difficult terrain. The modern Royal Welch Fusiliers and French Foreign Legion still maintain pioneer sections who march at the front of ceremonial parades, carrying chromium plated tools intended for show only. Other historic distinctions include long work aprons and the right to wear beards.

The dawn of the internal combustion engine marked the beginning of a very significant change for military engineering. With the arrival of the automobile at the end of the 19th century and heavier than air flight at the start of the 20th century, military engineers would absorbe a major new role to support the movement and deployment of these systems in war. Military engineers gained vast knowledge and experience in explosives. They are tasked with planting bombs, landmines and dynamite.

At the end of World War I, the standoff in the Western Front caused the Imperial German Army to gather experienced and particularly skilled soldiers to form "Assault Teams" which would break through the Allied trenches. With enhanced training and special weapons (such as flamethrowers), these squads obtained some success, but too late to change the outcome of the war. In early WWII, however, the Wehrmacht "Pioniere" battalions proved their efficiency in both attack and defense, somewhat inspiring other armies to develop their own combat engineers battalions. Notably, the attack on Fort Eben-Emael in Belgium was conducted by Luftwaffe glider-deployed combat engineers.

The need to defeat the German defensive positions of the "Atlantic wall" as part of the amphibious landings in Normandy in 1944 led to the development of specialist combat engineer vehicles. These, collectively known as Hobart's Funnies, included a specific vehicle to carry combat engineers, the Churchill AVRE. These and other dedicated assault vehicles were organised into the specialised 79th Armoured Division and deployed during Operation Overlord - 'D-Day'.

Other significant military engineering projects of World War II include the Mulberry harbour and Operation Pluto.

Modern military engineering still retains the Roman role of building field fortifications, road paving and the breaching of terrain obstacles. A notable military engineering task was, for example, the breaching of the Suez Canal during the Yom Kippur War.

Multi-national Institutions[link]

The NATO Military Engineering Center of Excellence (MilEng CoE) is co-located with the German Army Military Engineer School in Ingolstadt. Prior to becoming a NATO CoE, the institute was known as the Euro NATO Training Engineer Centre (ENTEC) and it was located in Munich. As ENTEC, the institute was mandated to conduct military engineer interoperability training for participating nations. As the MilEng CoE, the institute's mandate has expanded to include doctrine and NATO standardization agreements (STANAGs) related to military engineering.
