'Armoured personnel carriers' (APCs) are
armoured fighting vehicles developed to transport
infantry on the
battlefield. They usually have only a
machine gun although variants carry
recoilless rifles,
anti-tank guided missiles (ATGMs), or
mortars. They are not really designed to take part in a direct-fire battle, but to carry the troops to the battlefield safe from
shrapnel and
ambush. They may have
wheels or
tracks. Examples include the American
M113 (tracked), the
British FV 432 (tracked), the
French VAB (wheeled), the
German GTK Boxer (wheeled) and the Soviet
BTR (wheeled). More heavily armed and armoured are
Infantry fighting vehicles, which are designed for direct combat.
History

The
M113, one of the most common tracked APCs, on duty during the
Vietnam War.

Some forces practiced very dangerous
tank desant tactics before the widespread adoption of APCs
During
World War I, when the
tank was developed, the British
Mark V
★ tank was designed with a small passenger compartment to carry troops. By some definitions this can be considered the first armoured personnel carrier. The first specialised APC was the
Mark IX of
1918.
During World War II,
half-tracks such as the American
M3 and the German
SdKfz 251 played a role similar to the armoured personnel carriers that were developed later on. Another forerunner to the APC during this time was the British
Universal Carrier also known as the Bren Carrier for the weapon it was designed to carry. Often, APCs were simply
armoured cars with the capacity for carrying troops, but they evolved into purpose-built vehicles to suit the demands of motorised warfare from
World War II.
In
1944, the commander of
2nd Canadian Corps, General
Guy Simonds, ordered the conversion of 72
US-produced
M7 Priest self-propelled
howitzers to personnel carriers. They were, at the time, being replaced by the British
Ordnance QF 25 pounder, and no future plans had been drawn up for them. The howitzer was removed, and the resulting hole was plugged with whatever steel was available. The vehicle was called
Kangaroo, after the workshop which did the conversion, which was codenamed Kangaroo. Later in the war Canadian-built
Ram tanks were used as a basis for the majority of conversions, as they were replaced by US Sherman tanks, and the original Kangaroos were converted back to self-propelled howitzers and returned to American forces.
After the war different specialised APCs were developed. The United States developed a series of tracked vehicles, culminating in the
M113 "box on tracks", of which 80,000 were made. The
Soviet Union developed the wartime
BTR-40 into a series of 8-wheeled APC.
At the end of the
1980s,
Israel converted captured
T-55 tanks to APCs, reminiscent of WWII conversions. The result is one of the best protected APCs in the world, called
IDF Achzarit.
The
infantry fighting vehicle is a development of the armoured personnel carrier concept.
Technology

Most armoured personnel carriers use a
diesel engine comparable to that used in a large
truck or in a typical city
bus (APCs are often known to troops as 'Battle Taxis' or 'Battle Buses'). The M113 for instance used the same engine as the standard
General Motors urban bus.
Most APCs are amphibious. Usually tracked APCs are powered by their tracks in the water, and wheeled APCs have propellors or
water jets. Preparations for amphibious operations usually comprises checking the integrity of the hull and folding down a trim vane in front. Swimming required fairly still waters, and good entry and exit points. Speed in water is typically 3-6 km/h.
Armour on APCs are usually composed of simple steel or
aluminium, sufficient for protection against small arms fire and most shell fragments. Just about any type of anti-tank weapon can defeat the armour of an APC.
The usual armament for an APC is a 12.7 (.50") or 14.5 mm heavy
machine gun. This is mounted on top of the vehicle, either on a simple
pintle mount, sometimes with a gun shield, or a small turret. Sometimes an automatic
grenade launcher is used instead.
