An Engineer Light Ponton Company was a combat engineer company of the United States Army that served with U.S. Army ground forces during World War II. [1] It was primarily a highly mobile pontoon bridge construction unit, though it also provided both M2 assault boats and a selection of infantry support bridging, ferries, and rafts. [1]
The combat engineer unit was organized and trained to transport and maintain its stream-crossing equipage, to construct floating bridges and rafts with this equipage, to guard and maintain completed bridges, to regulate traffic thereon, and to dismantle bridges and rafts. They are responsible for construction of floating bridges and rafts assisted by general engineer troops. Light ponton companies may be attached to divisions engaged in stream-crossing operations in accordance with the tactical situation.
Company capabilities included, but were not limited to: [2]
The light ponton company consisted of a headquarters platoon, two bridge platoons, and a light equipage platoon. Its equipment included:
This platoon consisted of company headquarters and a service and repair section. Company headquarters-officer personnel consisted of the company commander and an administrative officer.

Platoon headquarters-The platoon headquarters supervised and controlled activities of the ponton section, and was responsible for installation, maintenance, and operation of its field telephone equipment. The ponton section transports one unit of bridge equipage.
This platoon consisted of platoon headquarters, an assault boat section, a raft section, and a footbridge section. The platoon headquarters was responsible for the care and safe transportation of the equipage assigned to the platoon. The assault boat section cared for and transported M2 assault boats. The raft section cared for and transported the infantry support rafts and ferry sets. The footbridge section was responsible for maintaining and transporting footbridge units.
The company was equipped with basic engineer tool sets, including a motorized air compressor, a truck-mounted crane, and tractor-mounted angledozers. They also supported stream-crossing equipment stocked in engineer depots. This included:
The light ponton company had sufficient organic transportation for simultaneous movement of all personnel, equipment, and supplies.
Individual weapons included carbine and pistol. Supporting weapons included .30 caliber heavy machine guns and .50 caliber machine guns.
Unit training included care and operation of transportation and heavy equipment assigned to the company, and nomenclature, use, repair, and maintenance of bridge equipage and light stream-crossing equipage. Engineers were trained in use of pontoon equipage including employment of outboard motors and training in repair of equipage is confined to repairs readily accomplished.
They engaged in frequent drills and field training in safe and rapid transportation of bridge equipage to crossing sites; in unloading and launching of equipage; in construction of bridges and rafts; in operational maintenance, care, guarding, and dismantling of bridges and rafts; and in loading of component parts on company vehicles.
Special effort was made in training to keep the bridge clear of drift and other floating objects, especial attention being given to anchor cables. Training in guarding bridges is of vital importance to insure uninterrupted flow of traffic.
Training all personnel in road movements including organization of columns, movements under cover of darkness, secrecy and discipline, security, and other fundamental principles prescribed in Army Field Manual FM 25-10. They were also trained in concealment of vehicles.
Combat training included the use of individual and supporting weapons for local security. Proficient gun crews were to be developed for employment of machine guns under defensive combat conditions.

A battalion is a military unit, typically consisting of up to one thousand soldiers commanded by a lieutenant colonel and subdivided into a number of companies, each typically commanded by a major or a captain. The typical battalion is built from three operational companies, one weapons company and one headquarters company. In some countries, battalions are exclusively infantry, while in others battalions are unit-level organisations.
A company is a military unit, typically consisting of 100–250 soldiers and usually commanded by a major or a captain. Most companies are formed of three to seven platoons, although the exact number may vary by country, unit type, and structure.
A platoon is a military unit typically composed of two to four squads, sections, or patrols. Platoon organization varies depending on the country and the branch, but a platoon can be composed of 20–50 troops, although specific platoons may range from 10 to 100 people. A platoon is typically the smallest military unit led by a commissioned officer. The platoon leader is usually a junior officer—a second or first lieutenant or an equivalent rank. The officer is usually assisted by a platoon sergeant.
A pontoon bridge, also known as a floating bridge, uses floats or shallow-draft boats to support a continuous deck for pedestrian and vehicle travel. The buoyancy of the supports limits the maximum load that they can carry.
The 11th Armored Cavalry Regiment is a unit of the United States Army garrisoned at the Fort Irwin National Training Center in California. The regiment has served in the Philippine–American War, the Pancho Villa Expedition, World War II, the Vietnam War, Gulf War and Iraq War.

The Singapore Combat Engineers (SCE) is a formation of the Singapore Army. Combat Engineers provide mobility by bridging gaps and clearing minefields to facilitate speedy advance of troops into enemy territory, and counter-mobility by constructing obstacles such as anti-tank ditches to impede the enemy's movement. The Combat Engineers also construct trenches, drainage systems and other related infrastructure to enhance the survivability of troops during operations.
