Used by Boko Haram and ISWAP fighters as vehicle-delivered explosive weapons in attacks on Nigerian and regional force positions, including documented 2021 Mallam Fatori fighting and a 2025 New Marte attack where troops recovered an explosive-rigged SUV.
Munitions
Vehicle-borne improvised explosive device (VBIED)
Also known as
- VBIED
- Car bomb
- Truck bomb
- Suicide vehicle-borne improvised explosive device
- SVBIED
- Up-armored SVBIED
A vehicle-borne improvised explosive device, or VBIED, is a car, truck, SUV, trailer, or other ground vehicle adapted to carry and deliver an explosive charge. The record covers car bombs, truck bombs, SVBIEDs, and up-armored assault vehicles documented across insurgent and jihadist conflicts from Iraq, Syria, Afghanistan, Somalia, Yemen, Nigeria, and the Second Intifada.
Role in Conflicts
- Side
- Islamic State
Islamic State forces used VBIEDs and VBIED facilities in the Iraq-Syria campaign; CENTCOM documented coalition strikes on an ISIL VBIED near Kobani, a VBIED facility in Fallujah, and more than 60 vehicle bombs destroyed during the Mosul operation.
Iraqi insurgent forces used VBIEDs during the post-invasion insurgency, with U.S. Army history documenting growth from suicide car-bomb attacks in 2003 to 133 VBIED attacks in 2004.
Role details- Side
- Islamic State
Islamic State forces used VBIEDs against Iraqi security forces and civilians; CJTF-OIR described a Makhmur-area VBIED facility as helping produce numerous VBIEDs for use across Iraq.
ISIL used VBIEDs and SVBIEDs during Syrian Civil War fighting, including BMP and gate-breach assault vehicles described in U.S. Army threat reporting and an OIR strike on a Daesh VBIED factory near Abu Kamal, Syria.
Role details
Taliban and Islamic State-linked armed groups used vehicle-delivered bombs in Kabul, including truck, car, and ambulance attacks documented by Human Rights Watch during the war.
Role detailsAl-Shabaab used VBIEDs in Somalia, including a January 2017 perimeter breach at a Kenya Defence Forces camp at Kulbiyow and a two-VBIED attack near Mogadishu's airport complex.
AQAP used vehicle-borne IEDs during the Yemen conflict, with U.S. State Department reporting vehicle-borne IEDs among AQAP attack methods in Yemen.
Role detailsPalestinian Islamic Jihad used VBIEDs against Israeli bus targets during the Second Intifada, including the 2002 Karkur Junction Line 841 bus attack.

Specifications
- Designation
- Improvised explosive device delivered by or concealed in a ground-based vehicle
- Delivery platform
- Ground vehicles including cars, SUVs, vans, trailers, trucks, large goods vehicles, motorcycles, or captured military vehicles
- Construction standard
- Not standardized; device layout varies by operator, available vehicle, available explosive material, concealment needs, and intended target
- Explosive payload
- Variable; limited by vehicle capacity, available explosive material, and tactical purpose
- Initiation
- May use attacker-controlled, suicide, time, or other IED switch categories depending on device design
- Primary effects
- Blast, fragmentation, fire, structural damage, and secondary fragmentation from surrounding materials
- Tactical employment
- Parked or concealed attack, moving/suicide assault, gate or perimeter breach, convoy attack, or first stage of a complex attack
- Detection challenge
- Common local vehicles can blend into traffic or parking areas; suspicious indicators include abnormal loading, altered interiors, concealed cargo, or unusual parking and driving behavior
Threat Characteristics
A VBIED is best read as a delivery method rather than a fixed weapon model. The same designation can describe a parked car bomb, a large truck bomb, a suicide assault vehicle, or an up-armored breach vehicle. What links them is the use of a ground vehicle to move or conceal an improvised explosive charge close to the target.
Concealment
Civilian vehicles can blend into routine traffic, parking areas, access roads, or service entrances until they are searched, blocked, abandoned, or detonated.
Assault Use
SVBIEDs trade concealment for shock effect, using speed, armor, or supporting fires to reach gates, checkpoints, troop positions, and other hard targets.
Payload Limits
Payload is not a catalog constant. Vehicle size, explosive availability, concealment, and intended effect determine how large or visible the device can be.
Variants
VBIED is an umbrella designation for improvised explosive devices delivered by or concealed in ground vehicles. The useful distinctions are employment method, payload capacity, and whether the vehicle is protected for a frontal assault.
| Variant | Configuration | Designation notes |
|---|---|---|
| Car bomb | Concealed or parked VBIED | Passenger cars and similar civilian vehicles are used when concealment in normal traffic or parking areas is central to the attack.

| Truck bomb | High-capacity VBIED | Cargo vehicles, large goods vehicles, and trailers allow heavier explosive loads or different access profiles than passenger-car attacks.

| Suicide vehicle-borne IED (SVBIED) | Driver-initiated assault or breach vehicle | A driver-initiated VBIED used as an assault component against gates, fortified positions, convoys, or troop concentrations.

| Up-armored suicide vehicle-borne IED | Protected assault VBIED | An SVBIED with improvised armor intended to survive defensive fire long enough to reach the target area.
