The M10 tank destroyer was an American tank destroyer of World War II. After US entry into World War II and the formation of the Tank Destroyer Force, a suitable vehicle was needed to equip the new battalions. By November 1941, the Army requested a vehicle with a gun in a fully rotating turret after other interim models were criticized for being too poorly designed. The prototype of the M10 was conceived in early 1942, being delivered in April of that year. After appropriate changes to the hull and turret were made, the modified version was selected for production in June 1943 as the 3-inch Gun Motor Carriage M10. It mounted a 3-inch (76.2 mm) Gun M7 in a rotating turret on a modified M4A2 Sherman tank chassis. An alternate model, the M10A1, which used the chassis of an M4A3 Sherman tank, was also produced. Production of the two models ran from September 1942 to December 1943 and October 1942 to November 1943, respectively.
The M10 was numerically the most important U.S. tank destroyer of World War II. It combined thin but sloped armor with the M4 Sherman's reliable drivetrain and a reasonably potent anti-tank weapon mounted in an open-topped turret. Despite its obsolescence in the face of more powerful German tanks like the Panther and the introduction of more powerful and better-designed types as replacements, the M10 remained in service until the end of the war. During World War II, the primary user of the M10 tank destroyer was the United States, but many were Lend-Leased to the United Kingdom and Free French forces. Several dozen were also sent to the Soviet Union. Post-war, the M10 was given as military surplus to several countries, such as Belgium, Denmark, and the Netherlands, through the Mutual Defense Assistance Act or acquired through other means by countries like Israel and the Republic of China.
The M10 is often referred to by the nickname "Wolverine", but the origin of this nickname is unknown. It is possibly a postwar invention. Unlike other vehicles such as the M4 Sherman, M5 Stuart, or M7 Priest, the M10 was never assigned a nickname or referred to with one when used by American soldiers. They simply called it a "TD" (a nickname for any tank destroyer in general) beyond its formal designation.

U.S. combined arms doctrine on the eve of World War II held that tanks should be designed to fulfill the role of forcing a breakthrough into enemy rear areas. Separate GHQ tank battalions would support infantry in destroying fixed enemy defenses, and armored divisions would then exploit the breakthrough to rush into the enemy's vulnerable rear areas. U.S. tanks were expected to fight any hostile tanks they encountered in their attack, but the mission of destroying massed enemy armored thrusts was assigned to a new branch, the Tank Destroyer Force. Tank destroyer units were meant to counter German blitzkrieg tactics. Tank destroyer units were to be held as a reserve at the corps or army level, and were to move quickly to the site of any massed enemy tank breakthrough, maneuvering aggressively and using ambush tactics (charging or chasing enemy tanks was explicitly prohibited) to destroy enemy tanks. This led to a requirement for very fast, well-armed vehicles. Though equipped with turrets (unlike most self-propelled anti-tank guns of the day), the typical American design was more heavily gunned, but more lightly armored, and thus more maneuverable, than a contemporary tank. The idea was to use speed and agility as a defense, rather than thick armor, to bring a powerful self-propelled gun into action against enemy tanks.
After the formation of the Tank Destroyer Tactical and Firing Center at Camp Hood, Texas in November 1941, the Army began testing to standardize on a configuration for the new tank destroyer battalions. The Tank Destroyer board began to examine several hundred Ordnance Department prototype proposals for a tank destroyer mounting a 3-inch gun, initially focusing the most interest on two:
- The T1, developed beginning in 1940 and standardized as the M5 3-inch Gun Motor Carriage in January 1941. It was a modified Cleveland Tractor Company airfield towing tractor mounting a 3-inch Gun T9 in a limited-traverse mounting A
- The T24, developed beginning in October 1941. The T24 was initially rejected as being too tall and the T40 was its improved derivative. The T40 was standardized as the M9 3-inch Gun Motor Carriage in May 1942. It was an M3 Lee chassis mounting a 3-inch Gun M1918 in a limited-traverse mounting B
Meanwhile, as the final design developments of these two tank destroyers were underway, the Ordnance Department became dissatisfied and by November 1941 had issued an additional specification for a tank destroyer with a 3-inch gun in a rotating turret. Design work began immediately. The 3-inch Gun Motor Carriage T35 combined an early-production M4A2 medium tank hull with the 3-inch Gun M7 from the M6 Heavy Tank in a cast, circular, open-topped turret. Using lessons learned from combat reports from the Philippines, the armor on the sides and rear of the upper hull was changed from flat to sloped plates. This new test vehicle was designated the 3-inch Gun Motor Carriage T35E1. Prototypes of these two vehicles were delivered to Aberdeen Proving Ground in April 1942, and the Army selected the T35E1 for further development on May 2, 1942. The side and rear upper hull armor of the T35E1 was thinned from 1 inch (25.4 mm) to 0.75 inches (19 mm) in order to reduce the weight of the vehicle. The staff at Aberdeen Proving Ground was worried that the armor of the T35E1 was too thin, and so bosses for appliqué armor panels were added to the hull sides, glacis, and turret sides. As the cast turret was found to be difficult to manufacture, the design of the turret was changed to a sloped pentagonal shape made of welded armor plate. In June 1942, the modified T35E1 was standardized as the 3-inch Gun Motor Carriage M10. By fall 1943, with its M5 and M9 competitors being eliminated from the design competition and their production contracts cancelled, the M10 was to become the United States' primary tank destroyer of the early war period.
As there were fears that the production of M4A2 chassis would be inadequate for M10 production, an alternate design, the 3-inch Gun Motor Carriage M10A1 based on the M4A3 medium tank chassis, was also authorized for production.
American tank destroyer doctrine emphasized speed and gun power over armor. As a result, the M10's armor was thin, which made it vulnerable to most German anti-tank weapons. The thickness of the M10's armor ranged from 0.375 to 2.25 inches (9.5 to 57.2 mm) The lower hull, being modified from that of a standard M4A2 or M4A3 Sherman tank, had 1 inch (25.4 mm) thick armor on the sides and rear, and an 0.5 inch (12.7 mm) thick floor. The rounded, cast transmission cover was 2 inches (50.8 mm) thick. In a departure from its M4 Sherman parent, the M10 lacked the extra 0.5 inch (12.7 mm) floor plate under the driver's and assistant driver's stations that provided them additional protection from mines.
The glacis plate was 1.5 inches (38 mm) thick, sloped at 55 degrees from the vertical. The sides and rear of the upper hull were 0.75 inches (19 mm) thick, sloped at 38 degrees from the vertical. The rear upper hull plate was used for storage of the vehicle's pioneer and maintenance tools; a 5-pound (2.27 kg) axe, a 5-foot (1.5 m) crowbar, a mattock handle and head, a double-sided 10-pound (4.54 kg) sledgehammer, and a track tensioning wrench. The sides and rear of the upper hull featured angled extensions or covers over the upper run of track. These extensions often got in the way of fitting "duckbill" extended end connectors, used to reduce ground pressure on soft ground, and were often removed, along with the front fenders, by maintenance units. The hull roof plate ranged from 0.75 in (19 mm) thick over the driver's and assistant driver's stations and turret ring, to 0.375 inches (9.5 mm) thick over the engine compartment.
The manually rotated turret of the M10 was a pentagonal shape. The sides were sloped 15 degrees inward from the vertical and were 1 inch (25.4 mm) thick. The rear of the turret was also 1 inch (25.4 mm) thick. The partial roof on the front third of the turret opening was 0.75 inches (19 mm) thick. The triangular cast gun shield sported the thickest armor on the vehicle, 2.25 inches (57.2 mm) It was sloped at 45 degrees from the vertical and horizontal.
The M10 and M10A1 were mechanically identical except for their power plants. The M10 used the General Motors 6046, consisting of two Detroit Diesel 6-71 inline engines mated to a common crankshaft. The tandem engine produced 375 horsepower (280 kW) at 2,100 rpm. One advantage of the GM 6046 was that the engines could be disconnected at will from the crankshaft and run independently. If one of the engines was damaged or destroyed, it could be disconnected and the other engine used to move the vehicle. The engine of the M10A1 was the Ford GAA, an 8-cylinder derivative of an ill-fated V-12 aircraft engine project. It produced 450 horsepower (335 kW) at 2,600 rpm. When tested side by side in September 1943, the M10A1 was judged to have superior automotive performance to the M10. Even though it produced only slightly less torque, the M10A1's engine was far lighter, and used a common fuel like the rest of the Army's vehicles (gasoline). By the time the test results were released in February 1944, the Army was committed to using the M10 overseas. As a result, the M10A1 was kept in the United States for training.
The M10 and M10A1 had a crew of five; commander, gunner, loader, driver, and assistant driver. The driver and assistant driver (who also operated the vehicle's radio) were seated in the front hull and provided with periscopes. The unique design of the hull hatches to clear the gun mantlet meant that the driver's view directly to the left side was obstructed. He was provided with a second periscope at the edge of the hull for this purpose. The commander, gunner, and loader were all located in the turret. The commander sat on a folding seat at the right rear. The gunner, on the left side of the gun, normally stood to operate it, but he was also provided with a folding seat. The loader normally stood in the area behind the gun. A third folding seat was provided in the turret for the assistant driver in case he needed to assist the loader for any reason.
The M10 lacked an auxiliary generator, which forced the crew to run the main engines in order to recharge the vehicle's batteries. The engine noise and smoke could attract enemy fire, especially in close quarters, where the M10 was vulnerable to due to its thin armor and open-topped turret. The lack of an auxiliary generator was rectified with the introduction of the M36 tank destroyer.
Soon after reaching production, it was realized that the barrel of the 3-inch gun M7 was too heavy, to the point where it prevented traverse of the turret on a slope of more than four degrees. As an attempt to improve the figure to fifteen degrees, the Army ordered that the track grousers and antiaircraft machine gun be stored on the rear of the turret. This did not solve the balance problem, and on 21 December 1942, triangular "quick fix" turret counterweights made of lead, mild steel, or cast iron were authorized. The mild steel parts weighed 2,400 pounds. Meanwhile, a set of wedge-shaped counterweights weighing 3,700 pounds total was designed by Fisher. The wedge-shaped weights began to be added to new vehicles at Fisher on 25 January 1943. By late December 1942, a second lock was added to the turret and a stirrup-shaped gun cradle was added to the rear deck to secure the gun for travel.
Since the track grousers could not be stored on the rear of the turret anymore, grouser racks that could be attached to the appliqué armor bosses on the hull were added to vehicles beginning in early April 1943. The M10 initially lacked any provision for indirect fire. In May 1943, an azimuth indicator and gunner's quadrant were added to the M10. The grouser racks and indirect fire equipment were often retrofitted to earlier vehicles. By late June 1943, it was realized that Fisher's initial counterweights were too heavy. Two newly designed counterweights reduced the total weight to 2,500 pounds and better distributed the weight of the gun. They resembled an upside-down "duck bill" shape when viewed from the side. To accommodate the new weights, the design of the upper rear of the turret was changed from sloped inwards to nearly vertical. In July 1943, the appliqué armor bosses on the hull sides and turret were dropped from production. The bosses on the glacis were retained. In late September 1943, a single M10 was tested with an Oilgear hydraulic traversing motor that could traverse the turret even without the counterweights, but this modification was not pursued as the production contracts were reaching their end.
Production of 4,993 M10s by the Fisher Body division of General Motors at the Fisher Tank Arsenal in Grand Blanc, Michigan ran from September 1942 through December 1943. Ford Motor Company built 1,038 M10A1s from October 1942 until September 1943. From September to November 1943, Fisher built the remaining 375 M10A1s. Fisher also completed a further 300 M10A1 hulls without turrets in January 1944 for direct conversion to M36 tank destroyers. From January to June 1944, 209 M10A1 vehicles were subsequently converted to M35 Prime Movers by removing the turret and adding the necessary equipment for them to tow the 8-inch Gun M1 and 240 mm Howitzer M1
1,413 M10A1s, including the 300 hulls manufactured in January 1944, and 724 M10s were eventually converted into M36 tank destroyers.

The M10 tank destroyer used an M4A2 medium tank chassis (M10A1s used an M4A3 chassis) with an open-topped manually traversed turret mounting the 3-inch Gun M7, in the M5 mount. The M7 gun weighed 1,990 pounds. The gunner stood or sat on the left side of the gun, and aimed it using the M51 or M70G telescope. An M12A4 panoramic telescope was also provided on the right side of the turret for indirect fire use. The M10 carried 54 rounds of 3-inch ammunition, 48 of which were stowed In four racks in the sponsons, and 6 rounds in the upper rear of the turret. For combat use, the 3-inch Gun M7 could fire five types of ammunition:
- M79 AP-T shot
- M62/M62A1 APCBC/HE-T shell
- M42A1 high explosive shell
- M88 HC B1 (hexachloroethane smoke) shell
- T4 (M93) HVAP-T shot
The M79 AP shot could penetrate 92 mm of homogeneous armor angled at 30 degrees from the vertical at 1,000 yards. The M62/M62A1 APCBC/HE-T shell was capable of penetrating 88 mm of homogeneous armor angled 30 degrees from the vertical at 1,000 yards. The rare T4 (M93) HVAP shot that saw action in small numbers beginning in September 1944 was capable of penetrating 135 mm of homogeneous armor angled at 30 degrees from the vertical at 1,000 yards. This shot featured a sub-caliber tungsten carbide penetrator encased within a steel jacket and aluminum body and ballistic "windshield". It was standardized as the M93 in February 1945. By March 1945, about 18,000 rounds of this special ammunition had been delivered to the European Theater, 58 percent of which were 3-inch projectiles. The M42A1 high explosive shell was used for indirect artillery fire or against fortifications and soft targets like infantry in trenches or antitank guns. The M88 hexachloroethane smoke shell was used to create smoke screens, or to flush enemy infantry out of buildings or fortified positions.
A .50 caliber (12.7 mm) Browning M2HB machine gun could be mounted on the top rear of the turret for use against enemy infantry and for anti-aircraft use, along with 300 rounds of ammunition stowed in 50-round boxes under the vehicle subfloor. The crew also had their personal weapons for self-defense. A Thompson submachine gun with 460 rounds of ammunition was stowed on brackets in the right rear of the turret for use by the vehicle commander. The other four crew members were armed with M1 carbines, each carrying as much ammunition on their person as they saw fit. An M1903 Springfield rifle with 60 rounds of ammunition was stowed next to the assistant driver, and an adapter for the rifle and ten antitank rifle grenades were stowed under the left front vehicle subfloor. Storage boxes in the turret held five fragmentation grenades, five smoke grenades, and two thermite grenades.
United States Army
The M10's heavy chassis did not conform to the quickly evolving tank destroyer doctrine of employing very light high-speed vehicles, and starting in the summer of 1944 it began to be supplemented by the fast M18 tank destroyer. American tank destroyer doctrine called for tank destroyers to be kept in reserve and rushed forward to counter massed enemy armored attacks. In reality, this was not the case and M10 battalions were attached, often semi-permanently, to infantry and armored divisions to provide additional direct and indirect fire support. Typical missions included providing indirect artillery fire by augmenting divisional artillery units, following and supporting the lead elements of an infantry assault, attacking obstacles such as fortifications and enemy vehicles (including tanks) that hampered the advance of friendly units, and setting up an antitank defense once the objective was secured.
The combat debut of the M10 came on 23 March 1943, during the Battle of El Guettar, part of the North African campaign. The M10 was initially successful as its M7 3-inch gun could destroy most German tanks then in service. During the battle, M10s of the 899th Tank Destroyer Battalion and M3 Gun Motor Carriages of the 601st Tank Destroyer Battalion accounted for 30 German tanks destroyed, although 20 M3s and 7 M10s were lost. The M10 did not see much tank-to-tank action for the rest of the North African campaign, and instead was used as mobile fire support.
During tank fighting in the Normandy campaign, the M10's 3-inch gun was proven to be ineffective against the thick frontal armor of the German Panther tank. On 6 July 1944, Eisenhower's headquarters requested that all M10 battalions be converted to the new M36 as soon as possible. On 10 July 1944, the 899th Tank Destroyer Battalion blunted a German counterattack by the Panzer Lehr Division near Le Desert and accounted for 12 Panthers, one Panzer IV, and one Sturmgeschütz III in a fierce two-day battle, most of it taking place at ranges of less than 200 m. Due to the initial shock of encountering heavy German tanks, further changes were made in the tank destroyer force in late September 1944. American officials requested that of the 52 battalions then committed to the European theater, 20 be converted to the M36, 20 retain the M10 or M18 at the discretion of their commanders, and the 12 towed battalions be re-equipped with the (then-prototype) T5 90 mm towed gun. By October 1944, the improved 90 mm Gun Motor Carriage M36 began to arrive in Europe, and mostly replaced the M10 by the end of the war. The plans to retain any towed battalions at all were canceled after their generally poor performance and high losses in 1944, especially during the Battle of the Bulge.
In the Italian campaign, as in northern Europe, the M10s were normally attached to infantry or armored units as infantry support or mobile artillery, more so the latter because of the general lack of German armor in that theater. Many US divisional commanders asked for their M10s to be replaced with fully armored tanks. In the Pacific war, due to the lack of serious Japanese tank opposition, US Army M10s were not used as tank destroyers, but as mobile artillery and infantry support. The M10 proved unpopular in the Pacific due to its open turret, which left it vulnerable to Japanese close-assault antitank tactics.
A total of 1,648 M10s were supplied by the United States to the British Army via the Lend-Lease program. British M10s were designated as 3in SPM M10. The M10 with the "wedge" counterweight was known as the 3in SPM M10 Mk I and the M10 with the "duck bill" counterweight was designated the 3in SPM M10 Mk II. 1,017 of the vehicles were up-gunned with the powerful 17-pounder gun from May 1944 to April 1945. A nickname used within the Department of Tank Design for both the 3-inch and 17-pounder versions was "Achilles"; the name was not used by troops during the war. The 17-pounder conversions were designated various ways, with a "C" suffix added on to the "M10" designation, or called "17pdr M10". Most of the vehicles converted were the 3in SPM M10 Mk II, as the "duck bill" counterweight better balanced the heavy gun. The gun mantlet needed modification to accept the barrel. The 17-pounder was of a similar bore to the 3-inch gun M7, but was longer and used a larger propellant charge; it had far superior armor penetrating capabilities. The 17pdr SP was used by the British, Canadian and Polish armies in Italy and northwest Europe. As well as service with British forces in Northwest Europe, they were retained post-war. Those not upgunned were stripped of their turrets and used as artillery tractors.
In British service, as self-propelled anti-tank guns, the M10 was operated by regiments of the Royal Artillery. Typically, two batteries had M10s while the other two batteries had the towed 17-pounder gun. One tactical theory was that the two towed batteries would form a gun line, while an M10 battery remained mobile on each flank to drive or lead enemy tanks to the static gun line. In practice, UK batteries were frequently separated in Normandy, M10s being seconded to British tank brigades equipped with Churchill tanks armed with the general purpose 75 mm gun just as were British 17 pounder conversions.
Free French Army
The Free French received at least 227 M10s, 155 of them through Lend-Lease. They served first in Italy, then in France and Germany. During the liberation of Paris in August 1944, a single M10 of General Leclerc's 2nd Armored Division named “Sirocco” disabled a Panther in the Place de la Concorde. French M10s also saw action on the French-German border around Strasbourg and in southern Germany; the Free French First Army led by General De Lattre received some when they were a part of the Sixth United States Army Group. French M10s were operated along similar lines as US tank destroyer units, although initially with five vehicles per platoon instead of four.
Approximately 52 M10s were supplied to the Soviet Union through Lend-Lease. They were used to form two self-propelled artillery regiments (SAP) The first was the 1223rd Self-propelled Artillery Regiment of the 29th Tank Corps, part of the 5th Guards Tank Army. This unit served on the 3rd Belorussian Front in 1944, taking part in summer campaigns in Belorussia, the Baltic, and East Prussia. The 1239th Self-propelled Artillery Regiment was part of the 16th Tank Corps, 2nd Tank Army. It fought in Belorussia and Poland in 1944.
Israel bought M10s from scrapyards and dumping grounds in Europe after 1948. The first batch arrived in 1951, being in very bad shape. Some years later, as the M10's guns were worn out, Israel decided to install 17-pounder guns and also French high-velocity 75 mm CN 75-50 guns that had just been bought. The M10s were repaired and entered service in 1955. After the 1956 war, they received the diesel engines of captured Egyptian Sherman tanks. It is believed that Israel also bought M10s from France and may have captured several from Egypt.
There is no report that the modified M10s were used by the Israelis in combat. They were withdrawn from service by 1966. 
The Egyptian Army had a small number of ex-British M10s, 3-inch and 17-pdr versions, and used them in 1948 against Israel. Israel captured some of them.
The M10's open-topped turret left the crew vulnerable to artillery and mortar fire and fragments. The 893rd Tank Destroyer Battalion took many casualties from artillery fire and tree bursts and lost 16 of 24 M10s during the Battle of the Hürtgen Forest. The crew was also exposed to sniper fire and infantry close assault, such as grenades thrown through the open turret, or attacks from upper story-windows, especially in urban warfare and wooded areas. In UK service, one M10 in the 86th Anti-Tank Regiment (XII Corps) in Normandy drove back out of action three times with the turret crew dead. Two turret crews had been killed by 88mm air bursts or mortars exploding in treetops and one crew was killed by a direct hit through the turret. The same driver survived each time. When this driver was placed with a new crew, his fourth, he was declared to be a 'Jonah' (bad luck) and they refused to drive with him. He was transferred to another unit and told to keep quiet about his history.
However, the open-topped turret gave excellent visibility, which was valuable for a vehicle that was tasked with finding enemy armored vehicles and other targets. The open top also made escape easier when the vehicle was hit and improved communications with accompanying infantry.
The M10 had a very slow turret rotation speed, as the turret traverse was unpowered and the crew had to use a hand crank to rotate the turret. It took approximately 80 seconds to rotate a full 360 degrees.
Total M10 losses in the European Theater of Operations to all causes were 539.

Despite not adhering strictly to the tank destroyer doctrine, the M10 still achieved impressive scores against enemy tanks. A US Army study of 39 tank destroyer battalions found that each destroyed, on average, 34 tanks, 17 towed guns, and 16 pillboxes. The tank destroyer battalions in the Third Army claimed the destruction of 686 tanks and 238 self-propelled guns. The highest-scoring tank destroyer battalion in the European Theater, the 823rd Tank Destroyer Battalion, claimed to have destroyed 113 panzers, including 27 Panthers and 18 Tigers, using towed guns and M10s. The 773rd Tank Destroyer Battalion also claimed to have destroyed 113 panzers, with the 702nd Tank Destroyer Battalion claiming 103. The 601st Tank Destroyer Battalion, which fought in North Africa, Italy, and Europe, claimed to have knocked out 155 tanks and self-propelled guns. Tank destroyers in the European Theater fired approximately 11 high-explosive (HE) rounds for every round of armor-piercing (AP) ammunition, an indication of their use in general support duties in addition to the intended mission of anti-tank defense.
