The M3 scout car (known as the White scout car in British Commonwealth service) was an American armored car produced in the World War II era, from 1939 to 1944. The original M3 scout car was produced in limited numbers, while the improved M3A1 scout car saw wide service during World War II and after.

Design

The main production variant, the M3A1 scout car, was a lightly armored, open topped, machine gun armed, four wheel drive vehicle designed to be used in the reconnaissance role. The M3A1 scout car was crewed by a driver and commander, while there was seating for six additional occupants in the rear.

Powered by a Hercules JXD 6-cylinder in-line petrol engine delivering 110 hp (82 kW), the M3A1 Scout Car had a maximum road speed of 50 mph (80 km/h) and the 30 US gal (110 L) fuel tank gave a maximum range of 250 mi (400 km). The vehicle’s four wheel drive and bumper mounted unditching roller enabled it to cross a 1.5 ft (0.46 m) wide trench and climb a 1 ft (0.30 m) high step, maximum fording depth was 28 in (0.71 m).

The armored body of the M3A1 Scout Car was produced by the Diebold Lock and Safe Company, it had a maximum armor thickness of 0.5 in (13 mm) and was open topped, providing good fields of view but no overhead protection for the occupants, a canvas cover was provided for protection from the elements. The underside protection was also limited, giving little protection from the effects of land mines for the vehicle’s occupants.

The M3A1 Scout Car was typically armed with a .5 cal (12.7 mm) M2 Browning heavy machine gun and one or two .30 cal (7.62 mm) M1919 Browning machine guns, all mounted on a skate rail upon which the pintle mounts could be moved about. Due to its open top, the occupants were also able to employ their personal weapons.

History

Development

M1 Scout Car

The M1 Scout Car was the first of a new series of armored cars developed by the White Motor Company for the US Army. Tested in 1934, the M1 Scout Car was an improvised, open topped four-wheel drive vehicle based on a commercial White ½-ton truck design. It weighed 3.85 short tons (3.49 t), was powered by a 75 hp (56 kW) engine, and had a top speed of 50 mph (80 km/h). The M1 Scout Car had a crew of four, a maximum armor thickness of 0.5 in (13 mm) and was armed with machine guns mounted on static mounts inside the vehicle. Seventy-six M1 Scout Cars were delivered to the US Army.

M2 Scout Car

The M2 Scout Car was a development of the M1, tested in 1935. The almost identical-looking M2 was larger and more powerful, and designed with as many commercial components as possible to keep costs down. It could accommodate a crew of seven. The M2 Scout Car weighed 3.95 short tons (3.58 t), was powered by a 94 hp (70 kW) engine and retained the top speed of 50 mph (80 km/h). Twenty M2 Scout Cars were delivered to the US Army.

M2A1 / M3 Scout Car

The M2A1 Scout Car, later redesignated the M3 Scout Car, was a further development of the M1 and M2 Scout Cars. The M2A1 / M3 Scout Car retained the 94 hp (70 kW) engine and had a top speed of 60 mph (97 km/h). Sixty-four M2A1 / M3 Scout Cars were produced, all being assigned to the 7th Cavalry Brigade.

M3A1 Scout Car

The M3A1 Scout Car was the final development of the series. Primary external differences from the M3 were a widening of the body over the fenders, the removal of the rear door of the M3 and the addition of the front roller. Internally, the M3A1 had an improved engine and was fitted with the machine gun skate rail. A total of 20,918 were produced between 1939–1944. It was the only version to see service outside of the United States, with the exception of Philippine Scouts in the 26th Cavalry Regiment (PS) who were issued the M2 variant before 1937.

Variants

The M3A1E1 Scout Car was developed to increase the range and fuel economy of the vehicle, it was powered by an 81 hp (60 kW) Buda-Lanova 6DT-317 six-cylinder diesel engine. 3,340 were produced, all were sent to the Soviet Union.

The M3A1E2 Scout Car was a version with an armored roof.

The M3A1E3 Scout Car was an experimental version fitted with a pedestal mounted 37 mm Gun M3.

The M3A1 Command Car was a command version, fitted with an armored screen and additional side armor.

The M2 Half Track was developed from the M3A1 Scout Car by adding half-tracks to the rear of the vehicle. The post-War BTR-40 was a Soviet development of the M3A1 Scout Car concept.

Service

United States

The M3A1 was used by cavalry units of the US Army in its intended cavalry role during the North African campaign and the invasion of Sicily, being employed for reconnaissance, screening and as an armored command vehicle. The M3A1 was fast and reliable, making it popular with its crews. However, it was a major disappointment in its intended role, because of its poor off-road performance and its lack of overhead protection. Cavalry units were forced to supplement it with the M2 Half-Track Car and the larger M3 Half-tracks.

Throughout 1943, most US Army units replaced the M3A1 with the M8 Greyhound armored car and the similar M20 Utility Car, although the M3A1 was retained for rear area security and convoy escort duties. A small number of M3A1s were employed in the Normandy campaign. A few M3A1s were used by the US Marine Corps in the Pacific theater, but none saw combat.

General George Patton used an M3A1 as a command vehicle, modified with additional armor and a raised fighting compartment.

A total of 11,401 M3A1 Scout Cars were allocated for supply to US allies under the Lend-Lease policy; 6,987 were supplied to the British Commonwealth, 3,310 to the Soviet Union and 104 to the Chinese Nationalist Army. Some were also supplied to Free Belgian, Free French, Czechoslovak and Polish forces.

Britain

In British Commonwealth service, the White Scout Car was regarded more as an armored truck, reflected in the designation "Truck, 15cwt, 4x4, Armoured Personnel", and was used in a variety of secondary roles, being issued to engineer, artillery (as an observation vehicle for field artillery observers) medical (as a protected ambulance) and signals units; within the Royal Armoured Corps’ Tank and Armoured Car Regiments it usually served in Squadron or Regimental headquarters. It was used by British Commonwealth forces in every theatre they fought in except Burma.

Soviet Union

In Soviet Red Army service, the M3A1 was used as an armored personnel carrier by brigade and corps reconnaissance units and motorcycle battalions and regiments, operating alongside the BA-64 armored car. The M3A1 was also used as an armored command vehicle and a gun tractor for the ZIS-3 76-mm field gun, although the towing hitch proved to be unreliable, the M3A1 remained in widespread service throughout the war.

China

The Chinese Nationalist Army received M3A1 Scout Cars from 1942 and used them throughout the Second Sino-Japanese War and the Chinese Civil War.

Postwar service

After the war, many vehicles were sold, mostly to Asian and Latin American countries while they remained in Soviet service until 1947. A few vehicles were used by Israel in the 1948 Arab–Israeli War. At least one Israeli M3A1 was modified with top armor and a revolving turret. France employed its M3A1s in the First Indochina War and the Algerian War. By late 1990, the only country with M3A1s remaining in service was the Dominican Republic.
