General info

M10 "Wolverine" in the Garage.

The 3-inch Gun Motor Carriage M10 (or the M10, unofficially the Wolverine) is a Rank II American tank destroyer with a battle rating of 3.7 (AB/RB) and 3.3 (SB). It was introduced in Update 1.49 "Weapons of Victory".

The main purpose, usage and tactics recommendations

General play style

Three "Circled Star" decals are applied to this M10 GMC.

The M10 has a powerful gun, good mobility and decent frontal armour (for tank destroyer standards). The best way to describe the M10 is calling it a counterpart to the M18 Hellcat with opposite trade-offs. The M18 Hellcat has mobility with paper thin armour whereas the M10 GMC has mediocre mobility with improved armour.

Vehicle characteristics

The M10 GMC takes much from the M4A2 Sherman which it was derived from. The drivetrain is identical with the drive shaft running from the engine in the rear to the front transmission and sprockets. The hull is sloped to a larger degree. The 3-inch (76 mm) cannon originally mounted on the experimental M6 Heavy Tank lacks the muzzle brake of the 76 mm M1A2 gun used on the later Rank III Sherman's and the M18 Hellcat. The turret is a pentagonal shaped M5 Mount type.

Tactics

The 3-inch (76 mm) cannon is a wonderful and powerful gun. APCBC ammo can penetrate any tank on the battlefield even from long range. The M10 also has AP ammo with no explosive filler that has higher penetration but does less post-penetration damage. Because APCBC has enough penetration, AP ammo is less useful although carrying a few of these shells could prove useful in certain situations. The tank has no problem being uptiered, as it carries the same gun as the 76 armed M4s, just with an inferior open-topped turret. It is not a bad idea to carry HE ammo as well to fight lightly armoured and open top tanks like the M16 SPAA. The powerful gun and potent ammunition makes the M10 a good sniper vehicle at its battle rating, especially with its -10 gun depression, giving the M10 the ability to maximize a hull-down position. Unfortunately, even though this tank destroyer does feature a turret, its rotation speed is extremely slow (< 4.0°/s) due to its historic configuration of only possessing a hand crank for the turret traverse. It is possible to crest a ridge and watch as your target rotates their turret, takes aim, and kills you, all while you are rotating your turret into position. Thus it is better to see it as a regular fragile SPG instead of a turreted SPG and fight from a distance and in possible concealment. Take warning that the gun's excellent penetration is too much for lower rank tanks and can lead to over-penetration, thus dealing less or even no damage to the enemy. Also, start each round with at least six missing shells (as detailed in the Ammo Racks section) to remove the ammo racks on the rear of the turret, reducing turret penetration vulnerability to an instant cook-off.

Weakspots: Side Armour profile

The armour of the M10 is quite decent for the rank and can make shells ricochet when angled properly, but nonetheless the armour is not thick enough to resist the stronger AT weapons of Rank II. The thickest part of the front hull is the 51 mm lower plate and the upper plate is 38 mm, though both are sloping at 55 degrees from vertical. The sides and back are only 19 mm slightly angled and thus can be penetrated by 12.7 mm fire or stronger. This fact is made worse by positioning of ammo racks on the sides, making it easy to one-shot the M10 with a side penetration. The turret has slightly better armour of 57mm angled at 45 degrees on the front but it is still very weak on the sides and back. The front of the turret can often eat shells as the shell will fragment on the initial armour, and the massive breach of the 76mm cannon will often absorb most if not all of the spalling, leaving the turret crew untouched. This will take you out of combat, but when backed up by team-mates it is possible to reverse away to repair. The turret top is exposed and because of that artillery barrages and HE shells are much more lethal to the crew. The M10 is known as an extremely viable target for strafing as with an open top it is one of the few vehicles that can be killed with only machine guns. The top mounted .50 cal provides some defence, but only works if aircraft are coming in from a low angle. Watching for enemy aircraft in the air is recommended, should the enemy have air superiority, hide in the nearest forest for top cover and concealment. One should avoid angling the armour a great degree as it may expose the weaker side armour at a more perpendicular angle.

Weakspots: Frontal Armour profile

The M10 has roughly the same mobility characteristics as the M4 Sherman’s. The top speed is 41 km/h, the same as the Sherman’s. Spaded, the tank moves surprisingly fast in a straight line, but the turning speed is a bit sluggish as well as the reverse speed. The M10 struggles while driving on inclines due to its narrow tracks. All in all the M10's mobility is moderate and it can get to its location reasonably fast.

The M10 is a support vehicle. Find a good sniping position and lay behind the team taking out enemy tanks from a distance. Try to stay away from enemy tanks to avoid getting killed quickly. If fighting in a close quarter’s environment, do not try to push forward without support. Stay back a couple of paces and let the teammates with heavier tanks charge in.

If in worse case a close quarter scenario is mandatory on maps such as Poland or Normandy, utilize the tank's turning speed to rotate the turret to the right angle. The M10 can turn faster than it can rotate and using its high speed when at high gear can produce some interesting skids via the physics engine to swerve the M10 to angle its gun at an enemy tank around the corner. It is recommended to understand and get a good feel of the M10's mobility and horsepower on dirt and paved roads before attempting this stunt.

Specific enemies worth noting

Counter-tactics

Destroying the M10 is not too hard a task. Though the armour is somewhat mediocre, do not underestimate its ability to make shells ricochet if angled. The gun mantlet can especially be problematic especially for HEAT shells. A smart player will use the M10 passively and will do a good job hiding the side armour. The best way to exploit the weakness of the M10 is to catch it off guard and take advantage of the abysmal turret traverse speed which greatly diminishes the response time for the M10.

In a situation where the M10 has to be faced head-on, the best place to shoot the M10 is to the upper left side of the hull. Doing so will knock out the gunner, though this most likely won’t knock out the tank. The follow-up shot should go to the upper right side of the hull and that should be the end of the M10. If the turret or the gun starts moving then shoot again at the first spot to knock the gunner out again. Shooting the front of the turret itself is usually not worth it due to the steep angling of the gun mantlet, most likely causing the shot to ricochet off. It is also a good idea to shoot the bottom of the hull to disable the transmission if the M10 is trying to flee.

Weakspots: Rear Armour profile

The M10’s side is lined with ammo racks and it’s extremely easy to one-shot the tank. Simply aim below the turret, shoot the side and the ammo should explode in a blaze of glory. If the ammo does not explode the first time, then try shooting the same spot again or aim more to the front of the hull to knock out any remaining crew. It is possible to blow up the fuel tanks or set it on fire by shooting the rear of the M10, worse case at least the engine will be disabled.

There is not a whole lot of places to shoot at the back of the M10, though a shot at the turret can knock out the turret crew. Two ammo racks are present at the rear of the turret, but these racks are most likely empty as 1) They are the first two to run dry and 2) Players will usually keep this empty with reduced ammo load. The best place to shoot in the rear would be the engine to immobilize the M10 and potentially set it on fire.

Pros and cons

Pros:

  • Main cannon penetration and damage is very good for the rank and BR, can knock out many tanks in one hit.
  • Mantlet sometimes absorbs shots with its sloped armour.
  • Good gun depression of -10°, perfect for hull-down positions.
  • Frontal glacis is somewhat bouncy due to it's steep angle.
  • 5 crew members to replace 3 incapacitated crew members, plus one more with Crew Replenishment modification.
  • Turret is sloped that can bounce some incoming shots.
  • Storage bustle on the rear of the turret helps protect it by absorbing shots aimed at it.
  • Turreted purpose-built tank destroyer allows for a 360 degree field of fire compared to casemate designs.
  • Pintle mounted HMG can offer effective anti-aircraft fire.
  • A lot of camouflages to unlock with relative ease.
  • Access to modification "Add-on Armour", that actually helps a lot.
  • Has relatively no problem when getting uptiered.

Cons:

  • One of the slowest turret traverse in the game.
  • Reload rate slower than other US tanks at its BR.
  • Top hull armour is extremely thin.
  • Easy to one-shot from the side by exploding the ammo rack.
  • Poor turning abilities, especially while not in motion.
  • Narrow tracks, which offer poor off-road performance.
  • Turret crew is exposed.
  • The vehicle is vulnerable when targeted by artillery barrages due to weak armour and exposed crew.
  • Very vulnerable to planes strafing from a high angle. Even light machine guns can take out the entire turret crew quite easily.
  • Below average reverse speed.

History of creation and combat usage

U.S. Tank Destroyer Doctrine

In 1940, the German Blitzkreig that overran Poland and France shocked the world by the effectiveness of the German armour. The standard anti-tank tactics used up to that point was for a line of anti-tank guns to be set up on a front, accompanying each infantry division. The problem was that the anti-tank guns were too thinly spread out to defend against a massed armoured attack on a single location.[1] In May 1941, Gen. Marshall, the U.S. Army chief of staff, ordered for a solution to this problem. The concept born from much discussion was to use a mobile anti-tank force that can be held in reserves and be deployed against a German armour attack, overwhelming the charging tanks with massed anti-tank power. The first few vehicles produced on this concept was the 37 mm GMC M6 and the 75 mm GMC M3. While adequate, these were only seen as a stop-gap measure until better tank destroyers could be developed. The type of vehicles to make up this mobile reserve was under much contention between two men, Lt.Col Andrew Bruce and Gen. Lesley McNair. Bruce, the head of staff planning the tank destroyer force, wanted a fast vehicle with a powerful gun. McNair, the senior commander of Army Ground Forces, believed the best anti-tank weapon were the towed anti-tank guns. In November 1941, the new, independent Tank Destroyer Branch was formed at Camp Hood, Texas; headed by Bruce. Plans were made to form 53 tank destroyer battalions, and much more were ordered after the breakout of war for America in December 1941. Initially armed with only the half-tracks and wheeled vehicles with the 37 mm and 75 mm cannons, it was decided that a stronger weapon was needed for the new branch.[2][3]

Development

Since the Tank Destroyer concept was made, there was a request for a 3-inch Gun Motor Carriage (GMC) design to become the standard tank destroyer. Up to 200 designs for a 3-inch GMC were sent from Ordnance for examination by the Tank Destroyer Board. Many were deemed unsatisfactory, but the urgency for vehicles had the Tank Destroyer branch prematurely standardize the 3-inch GMC M5 and M9 in January 1941 and May 1942 respectively. In November 1941, a proposal of a turret tank destroyer came in that would use the chassis of the new standard medium tank and armed with the 3-inch gun from the M6 heavy tank. The developed design would be designated the 3-inch GMC T35, an open-topped turret design. The initial design was an open traversable turret put on top of a chassis of the M4A2 Sherman. Combat reports from the Philippines conflict against the Japanese forces came in and criticized vertical armour for being easy to penetrate by anti-tank weapons. The criticism prompted the T35 to be redesigned into the T35E1, which used a sloped side hull armour instead of a vertical design and lowered the overall silhouette. The T35 and T35E1 were then delivered to the Aberdeen Proving Grounds in April 1942 for testing and demonstrations. During the tests, the T35 were compared to the M5 and M9. The T35 proved automotively superior and more well made than the other designs, and with their flaws brought into light, the M5 and M9 were soon cancelled. The rejections of the two other vehicles left the T35 and T35E1 as the sole contenders in options for a tank destroyer. By 2 May 1942, the Army decided to standardize the T35E1 variant. Small changes were made to the designs, such as changing from a cast turret to a welded one and thinning of the armour from 1 inch to 3/4 inches. The thinning of armour caused concerns on the vehicle's survivability and another proposal was to add bosses to be added on the hull front and side for application of appliqué armour if needed. The vehicle was standardized as the 3-inch Gun Motor Carriage in June 1942. [2]

The Tank Destroyer command did not like the M10. They wanted a highly mobile 3-inch GMC and the usage of the M4 medium chassis meant the M10 did not move any faster than the standard medium tanks. Bruce himself saw the M10 as an obstruction to a true tank destroyer and as another expedient model akin to the 75 mm GMC M3. He continued his support on the the T70 project, which would become the M18 Hellcat in 1943. The Army decided that an adequate vehicle was needed now and it was better than a perfect vehicle at a later date. Thus, the Army continued production of the M10, regardless of Tank Destroyer and Armored Forces’ opinions on it. The M10 was an adequate tank destroyer in that a single M10 costs about $47,900 to make while the M4A2 Sherman costs $60,200. The near 25% difference in price means the M10 could be produced in higher numbers for massed amounts of vehicles to act in the Tank Destroyer role. [2]

Production started on the M10s in September 1942 at Fisher Tank Arsenal at Grand Blanc, Michigan. The urgency for the vehicles caused the production priority of the M10 to be class AA1, a rating much higher than even the M4 Sherman. The standard M10 used M4A2 chassis with the twin GM 6046 diesel engines, but there was a concern that there would not be enough of the M4A2 chassis for the conversion, so a second variant was developed using the M4A3 chassis with the Ford GAA gasoline engine. The gasoline variant, designated the M10A1, would enter production in October 1942 at Ford Motor Company. Production of these two vehicles would run until December 1943 (M10) and January 1944 (M10A1) for a total production number of 6,706 vehicle produced, 4,993 M10s and 1,713 M10A1s.[2]

Today, the M10 is often referred to as the "Wolverine". However, the origin of this nickname is unknown. Some have contested that it was a British nickname, but it is unlikely as they gave it the designation "Achilles". It also is not an American nickname as well as all official documents referred to the M10's by their designation or "TD". It is widely accepted that "Wolverine" is a post-war nickname similar to the "Hetzer" nickname on the Jagdpanzer 38(t).[2]

Combat usage

European theater

The first units to receive the M10s were the 776th and 899th Tank Destroyer Battalions. The Army committed the more numerous diesel-powered M10s to the front while the gasoline M10A1s stayed as training vehicles back in the states. The M10s saw their first action at the Battle of El Guettar on 23 March 1943. The 899th supported the 601st (equipped with the M3 GMC) and fought off the 10th Panzer Division. The battle ended with 30 of the 50 German tanks involved destroyed, with the 601st suffering a loss of 20 of their 28 vehicles and the 899th losing only seven M10s. The Battle of El Guettar was the best example of the Tank Destroyers following their doctrine of moving reserve vehicles up to counter an enemy armoured attack. After El Guettar, there was only sporadic armour engagements and thus the M10s were sent back to the reserves. One officer, Lt.Col. James Barney of the 776th, did not like the idea of the M10s and other tank destroyers being wasted in the rear lines and developed a tactic for these vehicles to be used in an artillery role. This was a role that the M10s would see most of their action in during the fighting in the Italy and even in the Normandy campaign. After the Tunisian campaign concluded, all the TD battalions still using the 75 mm GMC M3 were converted to use the M10s.[2]

Despite its rather good performance in Africa, the M10 hit a snag when their usefulness was questioned. Some, like General Lucas, saw the TD branch as a failure; others, like General Patton and Bradley, saw their usage as being misplaced. These opinions and the field experience in Africa had McNair order for a change in TD policy in emphasis of the towed anti-tank gun, converting 15 self-propelled battalions to use towed guns. This change in direction for the tank destroyers caused a lowered interests on the M10s, and as such the M10 production would stop by the end of 1943. Regardless, M10s fought on in the combat theaters. The Italian Campaign did little to vindicate the M10s as it was found that the TD battalions were using 15,000 HE shells a month by December 1943 in the artillery fashion devised by Barney. The lack of major German armour presence forced the tank destroyers to take up an artillery role in Italy to be any form of use in the campaign. There were sporadic encounters with the new Ferdinands and Panther tanks against the M10, but these small encounters made little impact to the tank destroyer’s confidence in their firepower, leading to the belief that their guns were still adequate up until the Normandy Campaign.[2]

When the Allies invaded France in June 1944, 30 TD battalions were present on the field. 11 were the towed while the rest had M10s or the new M18 Hellcats. The experience in France did show that the self-propelled mounts were much more preferable than the towed variants, the towed guns being too slow and unwieldy while providing little protection to the crew. Of the two gun mounts, the M10 became one of the most preferred tank destroyer in the campaign.[2] This is because the M18 Hellcat was criticized for its thin 1/2 inch and that its main advantage, the high speed that Bruce had pushed for, fell short when the Tank Destroyer doctrine is made redundant with the lack of German armour present in Normandy.[3] Overall, the tank destroyers served in an infantry support role in most of the Normandy campaign, a role the M10 was not optimized in for many reasons. The open top exposed the crew to sniper fire and grenades, the thin armour could not withstand most German anti-tank weapons, and the lack of powered traverse in the turret caused the M10 to have a long traverse rate. Nevertheless, the M10s proved to be a very inspiring vehicle on the field and helped American soldiers push deeper into France. The first major tank engagement for the Americans in Normandy was around July 10 when the Panzer Lehr Division, made up of Panthers and other vehicles, attacked near Isigny. The 899th TD battalion stationed in the sector fought off the division. While the 899th destroyed 12 Panthers, the experience shocked the crews when they found the Panther invulnerable to frontal shots from the 3-inch gun. The realization that the M10s were now underpowered against the new German tanks caused a general complaint among the TD battalions for the fielding of a better gun on the field. The response to this would not come for three months, and in that time the TD crews had to make do with what they had.[2]

As the Allies moved on into Fall 1944, the M10 tank destroyer units were undergoing a transition into the new 90 mm GMC M36, a M10 chassis with a turret armed with the more powerful 90 mm cannon. Though it was met with enthusiasm by the TD crews, the priority is low due to the low number of German armour encountered. The most important addition to the M10 units was the availability of the T4 HVAP rounds for the 3-inch gun. The new round allowed the M10s to penetrate a Panther’s mantlet from up to 1,000 yards, compared to the 200 yards with normal ammunition. Only 2,000 HVAP rounds came in November 1944, as such there was the issue of only being able to issue one HVAP round per M10. These shortages ensured that the tank destroyers were short-handed during the German offensive in the Battle of the Bulge. The M10, outnumbering the M36 and lacking adequate numbers of HVAP, faced against Panthers and Tiger IIs during the German Ardennes Offensive. The impact of the battle led to renewed interest in improving the tank and tank destroyers, leading to more 76 mm M4 mediums and 90 mm M36 to arrive in Europe. An interesting situation in the Battle of the Bulge is a deception mission by the Germans named Operation Grief, which had ten Panther tanks dressed up to look like M10s externally to fool Americans.[4] All of these mock-ups were destroyed by battle or scrapped after it. After the Battle of the Bulge, the majority of German armoured forces have been dwindled and armour engagements largely declined in the final months of the war in Europe.[2] One of the M10’s most notable action in 1945 was done on January 26 in the Colmar Pocket when the most decorated soldier of World War II, Audie Murphy, used a knocked out M10's M2 Browning machine gun to hold off a German counter attack of six tanks plus infantry while calling in artillery. He held for an hour and killed about 50 German soldiers from behind the burning M10 wreck, forcing the tank units to retreat due to loss of infantry support. Audie Murphy was awarded the Medal of Honor for his actions.[5][6]

After the end of World War II, M10s and other tank destroyers in US service became obsolete as well as the tank destroyer doctrine.[7] Mainly due to increasing prevalence of well-armoured tanks that could do its job more efficiently such as the M26 Pershing, but also the lack of German AFVs at the time of the war and a study on ammo usage indicates that the tank destroyers spent more time supporting infantry with high-explosive shells than killing tanks with armour-piercing, rendering the tank destroyer section an unnecessary component in the modernizing armoured forces.[2]

Other usage of the M10s

M10s were also sent to the Pacific Theater against Japanese forces. However, the setting of the theater was unsuitable for mass usage of the tank destroyers; as such, only seven TD battalions were allocated. The M10s were first used on Kwajelin with the 7th Division, but their usage were restricted to simply substituting the armoured forces. The M10s only saw usage as an infantry support vehicle due to the low number of Japanese tanks available in the campaign. The most action the M10s saw were at the Palaus Islands (Pelileu), Philippines, and Leyte. General reception of the tank destroyers in the Pacific Theater were unsatisfactory.[2]

The M10s were a part of the American Lend-Lease program to the Allies and as such many M10s found their ways into British, Free French, and Soviet hands. In all, 1,855 M10s were sent in the Lend-Lease program, of which 1,648 were to Great Britain. The British designated the M10s as the 3" SPM (Self-Propelled Mount) M10. The most famous of the British usage of the M10 was the conversion of the armament into the 17-pounder gun. These converted M10s were designated M10C or M10 17-pdr under British nomenclature, though they did issue a name Achilles to designate all forms of M10 under British service.[2]

After the war, most M10s were scrapped or given away as part of the Military Assistance Program to other allies. Its derivatives, the Achilles and the upgunned M36 GMC would see more usage in post-war service.[2]
