The Sd.Kfz. 251 ( Sonderkraftfahrzeug 251 ) half-track was a World War II German armored personnel carrier designed by the Hanomag company, based on its earlier, unarmored Sd.Kfz. 11 vehicle. The Sd.Kfz. 251 was designed to transport the Panzergrenadier (German mechanized infantry ) into battle. Sd.Kfz. 251s were the most widely produced German half-tracks of the war, with at least 15,252 vehicles and variants produced by seven manufacturers. The utility of this vehicle led the German Army to develop the similar looking but shorter and lighter Sd.Kfz. 250 as a supplement.
36-575: The STREIT Group Spartan is an armoured personnel carrier designed and built by STREIT Group ; it is also license produced by KrAZ (Kremenchuk Automobile Plant) in Kremenchuk , Ukraine . The Spartan can be used in a wide variety of applications, including military and police missions. Its welded steel body is mounted on the chassis of a Ford F550 . It is able to withstand ballistic assaults and protect against grenade and land mine blasts. The Ukrainian truck maker AutoKraz manufactures

The baseline Stryker carries an M2 on a Protector remote weapons system. APCs may be used as armoured ambulances , to conduct evacuations of wounded personnel. These vehicles are equipped with stretchers and medical supplies. According to article 19 of
108-450: A large production run, but was quite complex to build, involving many angled plates. From early 1943, the D model was developed with the purpose of halving the number of angled body plates, simplifying the design and thus speeding up the production. D models can be easily recognized by their single piece sloping rear, with flat doors. The standard personnel carrier version was equipped with a 7.92 mm MG 34 or MG 42 machine gun mounted at

Compared to infantry fighting vehicles (IFVs), which are also used to carry infantry into battle, APCs have less armament and are not designed to provide direct fire support in battle. Infantry units that travel in APCs are known as mechanized infantry . Some militaries also make a distinction between infantry units that use APCs and infantry units that use IFVs, with
180-446: A single squad of 10 panzergrenadiers to the battlefield protected from enemy small arms fire, and with some protection from artillery fire. In addition, the standard mounting of at least one MG 34 or MG 42 machine gun allowed the vehicle to provide suppressive fire for the rifle squad both while they dismounted and in combat. The armour plates were designed to provide protection against standard rifle/ machine gun bullets (like
216-552: A total of 27 armored half-tracks, of both the 251 and 250 types followed in 1944 by 251 type and other types of armored cars to convert two cavalry divisions into armored or mechanized divisions. Sd.Kfz. 251s were known as SPW mijlociu ("medium SPW") in Romanian service, while Sd.Kfz. 250s were referred to as SPW ușor ("light SPW"). The Army of the Independent State of Croatia received 15 Sd.Kfz. 251 in spring 1944 and
252-533: A whole were produced in large numbers. Czechoslovakia and Poland together developed the universal amphibious OT-64 SKOT . The BMP series is termed as infantry fighting vehicles , but it has a designed role of carrying troops to the battlefield. The BMP-1 , 2 , and 3 all possess the ability to transport troops. By convention, armoured personnel carriers are not intended to take part in direct-fire battle, but are armed for self-defence and armoured to provide protection from shrapnel and small arms fire. An APC
288-583: Is unmanned ground vehicle (UGV) version of KrAZ-Spartan. It was unveiled during the 2016 Arms and Security exhibition in Kyiv. The vehicle could be operated by a tablet, a smart glove or an operator control station. It uses WiFi / Wimax wireless networks to communicate with a range from 10 km to 50 km. It can transport ammunition, food, fuel and medicines to the combat zone. It also has ability to carry wounded troops to hospitals. Armoured personnel carrier An armoured personnel carrier ( APC )
324-508: Is a broad type of armoured military vehicle designed to transport personnel and equipment in combat zones. Since World War I , APCs have become a very common piece of military equipment around the world. According to the definition in the Treaty on Conventional Armed Forces in Europe , an APC is "an armoured combat vehicle which is designed and equipped to transport a combat infantry squad and which, as
360-420: Is either wheeled or tracked , or occasionally a combination of the two, as in a half-track . Wheeled vehicles are typically faster on road and less expensive, however have higher ground pressure which decreases mobility offroad and makes them more likely to become stuck in soft terrains such as mud, snow or sand. Tracked vehicles typically have lower ground pressure and more maneuverability off-road. Due to
396-757: Is the heavily armoured Israeli Achzarit , converted from captured T-55s tanks, the concept culminating in the Namer . Meanwhile, the Warsaw Pact developed their own versions of the APC. The Soviet Union termed theirs the Bronetransporter ( Russian : бронетранспортер ), better known as the BTR series. It comprised the BTR-40 , BTR-152 , BTR-60 , BTR-70 , BTR-80 , and the BTR-90 , which as

This level of armour provided protection against normal (non-tungsten) rifle AP round, which could pierce about 8mm of vertical armour. Positive aspects of the open top included greater situational awareness and faster egress by the infantry, as well as the ability to throw grenades and fire over
468-499: The Cold War , more specialized APCs were developed. The United States introduced a series of them, including successors to the wartime Landing Vehicle Tracked . The most numerous was the M113 armored personnel carrier , of which more than 80,000 were produced. Western nations have since retired most M113s, replacing them with newer APCs, many of these wheeled. A cold war example of a "Kangaroo"
504-649: The Geneva Conventions , "mobile medical units of the Medical Service may in no circumstances be attacked, but shall at all times be respected and protected by the Parties to the conflict". Although article 22 allows them to carry defensive weaponry, they are typically unarmed. Under Article 39, the emblem of the medical service "shall be displayed ... on all equipment employed in the Medical Service." As such, armoured ambulances are marked with International Committee of
540-452: The KPV , PKT and NSV machine guns are common options. In "open top" mounts the gunner sticks out of the vehicle and operates a gun on a pintle or ring mount. Ring mounts allow the gun to traverse 360 degrees, a pintle mount has a limited field of fire. It can be preferable to an enclosed gunner because it allows a greater field of view and communication using shouts and hand signals. However,
576-532: The American M3 and German Sd.Kfz. 251 played a role similar to post-war APCs. British Commonwealth forces relied on the full-tracked Universal Carrier . Over the course of the war, APCs evolved from simple armoured cars with transport capacity to purpose-built vehicles. Obsolete armoured vehicles were also repurposed as APCs, such as the various " Kangaroos " converted from M7 Priest self-propelled guns and from Churchill , M3 Stuart and Ram tanks . During
612-481: The French VAB . Armoured personnel carriers are designed primarily for transport and are lightly armed. They may be unarmed, or armed with some combination of light , general-purpose , heavy machine guns, or automatic grenade launchers . In Western nations, APCs are frequently armed with the .50 calibre M2 Browning machine gun , 7.62mm FN MAG , or 40mm Mk 19 grenade launcher . In former Eastern bloc nations,
648-541: The Israeli IDF Namer has as much armour as Merkava main battle tank . Armour is usually composed of steel or aluminium . They will also use ballistic glass . Many APCs are equipped with CBRN protection, which is intended to provide protection from weapons of mass destruction like poison gas and radioactive/nuclear weapons. Generally APCs will be lighter and less armoured than tanks or IFVs, often being open topped and featuring doors and windows, as seen in
684-505: The Red Cross ( ICRC ) recognized symbols . The infantry fighting vehicle is a derivative of the APC. Various classes of infantry fighting vehicles may be deployed alongside tanks and APCs, in armoured and mechanized forces. The fundamental difference between an APC and IFV is the role they are designed for. The CFE treaty stipulates an infantry fighting vehicle is an APC with a cannon in excess of 20 mm, and with this additional firepower
720-570: The Sd.Kfz. 251 was the large track area, with the characteristic "slack track" design with no return rollers for the upper run of track. The Sd.Kfz. 251 also had the Schachtellaufwerk system of overlapping and interleaved main road wheels common to virtually all German halftracks of the period. This lowered the ground pressure and provided better traction, at the cost of much greater complexity in maintenance. The Sd.Kfz. 251 also had tank steering, whereby

Variants were produced for specialized purposes, including with anti-aircraft guns, light howitzers, anti-tank guns and mortars or even large unguided artillery rockets , as well as a version with an infrared search light used to spot potential targets for associated Panther tanks equipped with infrared detectors. A strong design feature of
828-560: The gunner is poorly protected and at risk of injury in the event of vehicle rollover. During the Vietnam War , M113 gunners often suffered heavy casualties. Enclosed vehicles are equipped with turrets that allow the crew to operate the weapons system while protected by the vehicle's armour. The Soviet BTR-60 has an enclosed turret mounted with a KPV heavy machine gun with a PKT coaxial machine gun. The U.S. Assault Amphibious Vehicle, Personnel ( AAVP7 's) machine guns (an M2, .50 caliber MG and
864-519: The infantry following—who were needed to consolidate the territory acquired—still faced small arms and artillery fire. Without infantry support, the tanks were isolated and more easily destroyed. In response, the British experimented with carrying machine-gun crews in the Mark V* tank , but it was found that the conditions inside the tanks rendered the men unfit for combat. During World War II, half-tracks like
900-544: The integrity of the hull and folding down a trim vane in front. Water traverse speed varies greatly between vehicles and is much less than ground speed. The maximum swim speed of the M113 is 3.6 mph (5.8 km/h), about 10% its road speed, and the AAVP-7 can swim at 8.2 mph (13.2 km/h). Armoured personnel carriers are typically designed to protect against small arms and artillery fire. Some designs have more protection;
936-609: The latter being known as armoured infantry. One of the first armored vehicles to be used in combat was the Spanish Schneider-Brillié , which saw action in Morocco. It was built from the chassis of a Schneider P2-4000 bus and could carry 12 passengers. The genesis of the armoured personnel carrier was on the Western Front of World War I. In the later stage of the war, Allied tanks could break through enemy trenches , but
972-443: The limited service life of their treads , and the wear they cause on roads, tracked vehicles are typically transported over long distances by rail or trucks . Many APCs are amphibious , meaning they are able to traverse bodies of water. To move in water they will often have propellers or water jets , be propelled by their tracks, or driving on the river bed. Preparing the APC to operate amphibiously usually comprises checking
1008-417: The manufacturer of the vehicle; this has been questioned, and may have been only a postwar label. German officers referred to them as SPW ( Schützenpanzerwagen , or armored infantry vehicle) in their daily orders and memoirs. There were four main model modifications (Ausführung A through D), which formed the basis for at least 22 variants. The initial idea was for a vehicle that could be used to transport
1044-456: The normal steering wheel moved the front wheels, but after more turning of the steering wheel, the tracks are braked to cause turning, like on a tank. However, the interleaved and overlapping main road wheels shared a major problem with the Tiger I and Panther tanks that also used such roadwheel configurations - in muddy or winter weather conditions, such as those during a mud season ( rasputitsa ) or
1080-451: The roof or sides of the vehicle. Many feature a remote weapon system . Usually four-wheel drive, these IMVs are distinct from 8-, 6-, and 4-wheeled APCs (such as the VAB ), being closer in appearance to civilian armoured money and gold transporters . Sd.Kfz. 251 Some sources state that the Sd.Kfz. 251 was commonly referred to simply as " Hanomags " by both German and Allied soldiers after
1116-423: The structure of the nose armor, which comprised two trapezoidal armor panels - the lower of which had an engine cooling vent. The B model, which began production in 1940, eliminated the fighting compartment's side vision slits. The C model, which started production in mid-1942, featured a simplified hexagonal-shaped forward armored plate for the engine. Models A through C had rear doors that bulged out. The C model had

1152-546: The top of the fighting compartment as necessary while remaining under good horizontal cover. The downside, as with all armored personnel carriers of the era, was a major vulnerability to all types of plunging fire ; this included indirect fire from mortars and field artillery , as well as small arms fire from higher elevated positions, lobbed hand grenades , Molotov cocktails , and strafing by enemy aircraft. The first two models (Ausf. A and B) were produced in small numbers from 1939. Ausf. A and B models can be identified by
1188-402: The uparmoured M1114 HMMWV is a clear example of this. The addition of armour provides protection to passengers. M1114s have been largely replaced by purpose-built Mine Resistant Ambush Protected ( MRAP ) vehicles. IMVs generally feature a v-shaped underbelly designed to deflect mine blasts outwards, with additional crew protection features such as four-point seat belts, and seats suspended from
1224-418: The vehicle can withstand the blast of two DM51 high-explosive fragmentation hand grenades. Its roof hatch is designed to support a pivoting turret with or without a machine gun. A remote controlled weapon station (RWS) is also installable as per customer requirement that combines a machine gun and a quartet of RK-3 Corsar anti-tank missiles. Specifications: KrAZ-Spartam Self-Driving Armoured Vehicle
1260-535: The vehicle is more involved in combat, providing fire support to dismounted infantry. "Infantry mobility vehicle" (IMV) is a new name for the old concept of an armoured car, with an emphasis on mine resistance. They are primarily used to protect passengers in unconventional warfare . The South African Casspir was first built in the late 1970s. In the 21st century, they gained favour in the post-Cold-War geopolitical climate. Identical to earlier High Mobility Multipurpose Wheeled Vehicle (HMMWV) in design and function,
1296-808: The winter conditions, accumulated mud and snow could freeze solid between the road wheels, immobilizing the vehicle. The early production models of this vehicle were issued to the 1st Panzer Division in 1939 as the 'Ausf.A' or 'A-version'. There were 232 estimated Ausf.A units produced, which took place in Hannover's Hanomag, Büssing-NAG of Berlin-Oberschöneweide, Weserhütte of Bad Oeynhausen, Wumag of Görlitz, and F. Schichau shipyard of Elbing facilities. These vehicles were meant to enable Panzergrenadiere to accompany panzers and provide infantry support as required. In practice, there were never enough of them to go around, and most Panzergrenadier units had to make do with trucks for transport. In August 1943, Romania acquired
