The combat engineer's goals involve facilitating movement and support of friendly forces while impeding those of the enemy. Combat engineers build fighting positions, fortifications, and roads. They conduct demolitions missions and clear minefields using specialized vehicles. Typical combat engineer missions include construction and breaching of trenches, tank traps and other fortifications; bunker construction; bridge and road construction or destruction; laying or clearing land mines; and combined arms breaching. Typically, a combat engineer is also trained as an infantryman, and combat engineer units often have a secondary role fighting as infantry.
A general combat engineer is often called a pioneer or sapper, terms derived respectively from the French and British armies. In some armies, pioneer and sapper indicate specific military ranks and levels of combat engineers, who work under fire in all seasons, may be allocated to different corps, as they were in the former Soviet Army, or they may be organized in the same corps. Geomatics (surveying and cartography) is another area of military engineering but is often performed by the combat engineers of some nations and in other cases is a separate responsibility, as was formerly the case in the Australian Army. While the officers of a combat engineering unit may be professionally certified civil or mechanical engineers, the non-commissioned members are generally not.
Combat engineers are force multipliers and enhance the survival of other troops through the use and practice of camouflage, reconnaissance, communications and other services. These include the construction of roads, bridges, field fortifications, obstacles and the construction and running of water points . In these roles, combat engineers use a wide variety of hand and power tools. They are also responsible for construction rigging, the use of explosives, and the carrying out of demolitions, obstacle clearance, and obstacle construction, assault of fortifications, use of assault boats in water obstacle crossings, helipad construction, general construction, route reconnaissance and road reconnaissance, and erecting communication installations. Combat engineers build and run water distribution points, carrying out water filtration, and NBC decontamination when necessary, and storage prior to distribution.
All these role activities and technologies are divided into several areas of combat engineering:
Mobility Improving the ability of one's own force to move around the battlefield. Combat engineers typically support this role through reduction of enemy obstacles which include point and row minefields, anti-tank ditches, wire obstacles, concrete and metal anti-vehicle barriers, and Improvised Explosive Devices (IED) and wall and door breaching in urban terrain. Mechanized combat engineer units also have armored vehicles capable of laying short bridges for limited gap-crossing.
Countermobility Building obstacles to prevent the enemy from moving around the battlefield. Destroying bridges, blocking roads, creating airstrips, digging trenches, etc. Can also include planting land mines and anti-handling devices when authorized and directed to do so.
When the defender must retreat it is often desirable to destroy anything that may be of use to the enemy, particularly bridges, as their destruction can slow the advance of the attackers. The retreating forces may also leave booby traps for enemy soldiers, even though these often wreak their havoc upon non-combatant civilians.
Defensive fortifications are designed to prevent intrusion into the inner works by infantry. For minor defensive locations these may only consist of simple walls and ditches. The design principle is to slow down the advance of attackers to where they can be destroyed by defenders from sheltered positions. Most large fortifications are not a single structure but rather a concentric series of fortifications of increasing strength.
Combat engineers employ a wide range of transportation vehicles and equipment, and uses weapons unique to the engineers, including those used in land mine warfare.
Basic combat engineering tools include safe use of:
For obstacle breaching, including minefields, the combat engineers use a variety of vehicles, explosive devices and plastic explosives including:
Combat engineers are a key role in all armed forces of the world, and invariably found either closely integrated into the force structure, or even into the combat units of the national troops. In many countries, combat engineers are members of broader military engineering corps or branches. However, some nations have distinct combat engineering corps or branches which are separate from other types of military engineers. The Danish military engineering corps is almost entirely organized into one regiment of combat engineers, simply named Ingeniørregimentet ("The Engineering Regiment"). During the War in Afghanistan and the 2003–2011 Iraq War the US Army tasked its combat engineers with route clearance missions designed to counter rising threats of IEDs. To increase the effectiveness of these units EOD and mechanic teams are typically embedded with the combat engineer platoon. Due to rising IED threats US Army sends some combat engineers rank specialist or higher to complete Explosive Ordnance Clearance Agent training to familiarize themselves with types of unexploded ordnance..
The Basic Field Manual, Engineer Soldier's Handbook, 2 June 1943 (FM 21-105) was written to provide guidance to a new combat engineer in the United States.
1st Combat Engineer Battalion is a combat engineer battalion of the United States Marine Corps.

The 20th Engineer Brigade is a combat engineer brigade assigned to the XVIII Airborne Corps of the United States Army stationed at Fort Bragg, North Carolina. Although the brigade was identified as an airborne unit, not all of its subordinate units were airborne qualified—despite the airborne tab as part of the unit patch. Soldiers of the 20th Engineer Brigade provide various supportive duties to other Army units, including construction, engineering, and mechanical work on other Army projects.
Though its predecessor units have lineage that dates back before the American Civil War, the formation was not formally designated as the 20th Engineer Brigade until its activation on 16 August 1950, at Fort Leonard Wood, Missouri. Deploying overseas in November 1952, it supported construction projects in southwestern France until its return to the US on 10 September 1954. From then until its inactivation on 12 December 1958, it provided support to XVIII Airborne Corps.
Reactivated on 1 May 1967, at Fort Bragg, the brigade deployed to Vietnam where it supported American forces for several years and a dozen campaigns. The brigade was deactivated on 20 September 1971, as American forces withdrew from the country.Reactivated as an airborne brigade on 21 June 1974 at Fort Bragg, NC, the unit has since seen numerous overseas tours, including to Kuwait during the Gulf war, Kosovo, Afghanistan during Operation Enduring Freedom, and Iraq during Operation Iraqi Freedom and Operation New Dawn. It has also independently conducted various humanitarian missions in the United States and in other nations throughout the world.2nd Combat Engineer Battalion

5th Engineer Regiment is a Reserve unit of the Royal Australian Engineers. Originally raised as the "5th Combat Engineer Regiment" in 1995 from the 4th Field Engineer Regiment, it is based in Holsworthy, Sydney, with one of its sub-units based at the multi-user depot HMAS Harman, in Canberra and another at Orchard Hills in western Sydney. Some of the unit's subunits draw lineage from the 4th and 5th Field Companies, which were raised for service during World War I.In late 2013, the regiment was reorganised, when two sub-units – 101st Construction Squadron and the Littoral and Riverine Survey Squadron – were transferred from the 21st Construction Regiment, following the decision to disband that unit. The regiment subsequently assumed the designation of the "5th Engineer Regiment". The LRSS was transferred to the School of Military Engineering in January 2016, and as of 2017 was being utilised to evaluate several new capabilities as well as running several courses and camps.In November 2017, the regiment subsumed the disbanded 8th Engineer Regiment. This resulted in the transfer of the 6th and 14th Combat Engineer Squadrons, and the 102 Construction Squadron to 5 ER. As a part of this amalgamation, the 14th Combat Engineer Squadron was transferred from 8 ER intact, to be based at Adamstown, while the 6th Combat Engineer Squadron was reduced to a troop at Dundas, and the 102nd Construction Squadron also became a troop, subordinate to the 101st Construction Squadron.Canadian Army
The Canadian Army (French: Armée canadienne) is the command responsible for the operational readiness of the conventional ground forces of the Canadian Armed Forces. As of 2018 the Army has 23,000 regular soldiers, about 17,000 reserve soldiers, including 5,000 rangers, for a total of 40,000 soldiers. The Army is supported by 3,000 civilian employees. It maintains regular forces units at bases across Canada, and is also responsible for the Army Reserve, the largest component of the Primary Reserve. The Commander of the Canadian Army and Chief of the Army Staff is Lieutenant-General Jean-Marc Lanthier.
The name "Canadian Army" came into official use beginning only in 1940; from before Confederation until the Second World War the official designation was "Canadian Militia". On 1 April 1966, as a precursor to the unification of Canada's armed services, all land forces were placed under a new entity called Mobile Command. In 1968 the "Canadian Army" ceased to exist as a legal entity as the Royal Canadian Navy (RCN), Canadian Army (CA), and Royal Canadian Air Force (RCAF) were merged to form a single service called the Canadian Armed Forces. Mobile Command was renamed Land Force Command in the 1993 reorganization of the Canadian Armed Forces. In August 2011, Land Force Command reverted to the pre-1968 title of the Canadian Army.Canadian Military Engineers
The Canadian Military Engineers (CME) is the military engineer branch of the Canadian Armed Forces. Members of the branch who wear army uniform comprise the Corps of Royal Canadian Engineers (RCE; French: Corps du génie royal canadien).
The mission of the Canadian Military Engineers is to contribute to the survival, mobility, and combat effectiveness of the Canadian Armed Forces. Their roles are to conduct combat operations, support the Canadian Forces in war and peace, support national development, provide assistance to civil authorities, and support international aid programs. Military engineers’ responsibilities encompass the use of demolitions and land mines, the design, construction and maintenance of defensive works and fortifications, urban operations (hostile room entry), breaching obstacles, establishing/maintaining lines of communication, and bridging. They also provide water, power and other utilities, provide fire, aircraft crash and rescue services, hazardous material operations, and develop maps and other engineering intelligence. In addition, military engineers are experts in deception and concealment, as well as in the design and development of equipment necessary to carry out these operations.
The official role of the combat engineer is to allow friendly troops to live, move and fight on the battlefield and deny that to the enemy.FV180 Combat Engineer Tractor
The FV180 Combat Engineer Tractor or C.E.T. is an amphibious specialist armoured vehicle of the British Army and has been in general service since 1976. A tracked, lightly armoured vehicle, with amphibious capability, the CET is used by Royal Engineers in ground preparation for bridge construction and towing activities in the front line of battle, such as digging vehicle fighting pits, constructing earthen barriers, repairing roads, recovery of disabled vehicles from water and other obstacles, preparing riverbanks for vehicle crossings and clearing obstacles.List of units of the Canadian Army
