Car bomb

The result of a car bombing in Iraq.

A car bomb, or truck bomb, also known as a vehicle-borne improvised explosive device (VBIED), [1] is an improvised explosive device placed inside a car or other vehicle and detonated.

It is commonly used as a weapon of assassination, terrorism or guerrilla warfare, to kill the occupants of the vehicle, people near the blast site, or to damage buildings or other property. Car bombs act as their own delivery mechanisms and can carry a relatively large amount of explosives without attracting suspicion; in larger vehicles and trucks, weights of at least 7,000 pounds (3,200 kg) have been used, [1] for example, in the Oklahoma City bombing. Car bombs are activated in a variety of ways, including opening the vehicle's doors, starting the engine, depressing the accelerator or brake pedals or simply lighting a fuse or setting a timing device. [2] The gasoline in the vehicle's fuel tank may make the explosion of the bomb more powerful by dispersing and igniting the fuel.

Use as weapon

Car bomb in Iraq, made up of a number of artillery shells concealed in the back of a pickup truck.

Car bombs are effective weapons as they are an easy way to transport a large amount of explosives to the intended target. A car bomb also produces copious shrapnel, or flying debris, and secondary damage to bystanders and buildings. In recent years, car bombs have become widely used by suicide bombers.[ citation needed]

Provisional Irish Republican Army (PIRA) Chief of Staff Seán Mac Stíofáin defines the car bomb as both a tactical and a strategic guerrilla weapon. Strategically, it disrupts the ability of the enemy government to administer the country, and hits simultaneously at the core of its economic structure by means of massive destruction. From a tactical point of view, it ties down a large number of security forces and troops around the main urban areas of the region in conflict. [3]


Defending against a car bomb involves keeping vehicles at a distance from vulnerable targets by using roadblocks and checkpoints, Jersey barriers, concrete blocks or bollards, metal barriers, or by hardening buildings to withstand an explosion. Since the height of the Provisional Irish Republican Army (PIRA) campaign, the entrance to Downing Street has been closed, preventing the general public from getting near Number 10. Where major public roads pass near buildings, road closures may be the only option (thus, for instance, in Washington, D.C. the portion of Pennsylvania Avenue immediately in front of the White House is closed to traffic). Historically these tactics have encouraged potential bombers to target "soft" or unprotected targets, such as markets. [4]

Suicide usage

In the Syrian Civil War, and Iraq, the car bomb concept was modified so that it could be driven and detonated by a driver, but armoured to withstand incoming fire. The vehicle would be driven to its target area, in a similar fashion to a kamikaze plane of WW2. These were known by the acronym SVBIED (from Suicide Vehicle Borne Improvised Explosive Device) or VBIEDs. This saw generally civilian cars with armour plating added, that would protect the car for as long as possible, so that it could reach its intended target. Cars were sometimes driven into enemy troop areas, or into incoming enemy columns. Most often, the SVIEDs were used by ISIS against Government forces, but also used by Syrian rebels (FSA and allied militias) against government troops. [5] [6]

The vehicles became more sophisticated as time went, with armour plating on the vehicle, protected vision slits, armour plating over the wheels so they would withstand being shot at, and also in some cases, additional metal grating over the front of the vehicle designed to activate rocket propelled grenades before hitting the actual surface of the vehicle. [7]

In some cases trucks were also used, as well as cars. They were sometimes used to start an assault. Generally the vehicles had a large space that would contain very heavy explosives. In some cases, animal drawn carts with improvised explosive devices (ADCBIED) have been used, generally either mules or horses. Tactically, a single vehicle may be used, or an initial "breakthrough" vehicle, then followed by another vehicle. [8]
