Description

The ␗3-inch Gun Motor Carriage M10 is a rank II Chinese tank destroyer with a battle rating of 3.7 (AB) and 3.3 (RB/SB). It was introduced in Update 1.91 "Night Vision".

This Chinese vehicle is mostly identical to the US M10 GMC, however it does not have access to the Add-on Armor modification.

General info

Survivability and armour

Armour type:

• Rolled homogeneous armour
• Cast homogeneous armour (Gun mantlet, Transmission area)
• Structural steel (Counterweight)

Armour	Front (Slope angle)	Sides	Rear	Roof
Hull	38.1 mm (55°) 50.8 mm (7-55°) Transmission area	19.05 mm (38°) Top 25.4 mm Bottom	19.05 mm (28°) Top 25.4 mm (7-52°) Bottom	19.05 mm Front 9.5 mm Rear
Turret	25.4 mm (68-89°) Turret front 57.15 mm (0-47°) Gun mantlet	25.4 mm (24-47°)	25.4 mm (30-47°) Turret rear 50 mm (0-50°) Counterweight	N/A

Notes:

• Suspensions wheels are 20 mm thick, bogies are 10 mm thick, and tracks are 20 mm thick.
• Belly armour is 12.7 mm thick.
• Hull rear sides are protected by attached grousers that give 20 mm of extra armour.

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 tank 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 most weapons stronger than a 12.7 mm machine gun. This fact is made worse by the 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 with the gun mantlet having 57 mm 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 breech of the 76mm cannon will often absorb most if not all of the spalling, leaving the turret crew untouched. This will take the M10 out of combat, but when backed up by team-mates it is possible to reverse away to repair. The turrets top is exposed and because of that artillery barrages and HE shells are much more lethal to the crew. One should avoid angling the armour a great degree as it may expose the weaker side armour at a more perpendicular angle.

For those fighting the M10 from the front, firing towards the upper left side of the hull glacis (towards the right from the firing perspective) will be able to knock out both the driver and/or gunner if the shot penetrates in the right angle. If this does not completely destroy the tank, it certainly has crippled it and the follow-up shot should go towards the opposite side to knock out the rest of the crew. Repeat if necessary in cases where the crews are still active inside the tank. It is also a good idea to shoot the bottom of the hull to disable the transmission if the M10 is trying to flee.

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, the 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 or a shot in the hull can cripple the engine. 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.

Armaments

Main armament

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, the AP ammo is less useful, although carrying a few of these shells could prove useful in certain situations. 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 make 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 turret 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 the enemy rotates their turret, takes aim, and shoots the M10, all while the latter is rotating its 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.

Usage in battles

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 destroyed quickly. To make full use of its decent sniping capacity, find a spot that:

• Overlooks the battlefield, streets or some passage
• Is Away from the frontline
• Offer slopes or cover and bushes
• Is easily accessible

With a location like that, the M10 can utilise its -10° gun depression and use hull down. Its turret front and mantlet can consistently cause ricochets especially in a downtier. Looming behind bushes, an M10's well aimed shots should be able to knock out most enemy tanks at the battle-rating range from long range. Even if you get spotted, any slope or hard covers will provide protection for you.

If fighting in a close quarter's environment, do not try to push forward without support. Stay behind friendly tanks in order to support them without being shot at. If in an urban scenario on maps like Poland or Normandy, utilize the tank's turning speed to rotate the turret to the right angle. But, the best option is still to find a hull down location. For example, in Normandy, during arcade, the best location is towards the C point, where there are hills and dips that can be used to hide the hull, while giving a good view of the battlefield.

The M10 has a very slow turret rotation speed, but the M10 can traverse faster than it can rotate its turret and use its high speed when at high gear to produce some interesting skids via the physics engine to swerve the M10 and 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. The low turret rotation speed means that a M10 player must always be aware of where the enemy tanks are, because they will not be able to turn the turret quickly if the enemy is able to flank the M10. In addition, the M10's side armour is weak, and the ammunition storage is in the hull sides, so if the enemy is able to shoot the M10 at that location, it is very likely to explode the ammo rack and destroy the tank with one shot.

Enemies worth noting:

R3 T20 FA-HS: this vehicle is the exact opposite tank when comparing to an M10: extremely high top-speed, great traverse and fast gun rotation. A well-maneuvered R3 can easily circle around the M10 and shoot AP shells through the thin side, while the M10 struggles to get the gun on target even when traversing the hull with the gun. If you know an R3 is around, you better turn your hull towards the possible direction and be ready to engage. Move the hull with the gun to target quicker. Even if you miss, the M2 Browning can still penetrate the R3 and knock out its crews. Note that a side shot on the R3 does not guarantee a kill as the fuse might not get triggered, and the crew are pretty separated. The R3 can run away and repair for another attack. A frontal shot, however, is likely to one shot it as the crew are all lined up.

8,8 cm Flak 37 Sfl.: also known as the "flak truck", it is rather hard to knock out due to the fact that its armour is so thin that almost every shell will over-penetrate, dealing almost no critical damage. Plus this vehicle mostly face their side to the targets, making it even harder to kill them as the crew are all far apart. So it can usually take quite some hits and take out the shooters one by one. As the shooter, aim for the left side of its turret first to disable its gunner first, then knock out the rest of its crew (right turret & driving compartment). Do not hope that the M2 HB can kill all the the crew members; the "flak truck" 's armour is also angled enough for any MG to penetrate.

Modules

Tier	Mobility		Protection	Firepower
I	Tracks		Parts	Horizontal Drive
II	Suspension	Brake System	FPE	Adjustment of Fire	M79 shot
III	Filters		Crew Replenishment	Elevation Mechanism
IV	Transmission	Engine

First off get all protection modifications: Parts and FPE. After that move on to research modifications from the Firepower tree: Horizontal Drive, Adjustment of Fire, and the Elevation Mechanism. Lastly research the Mobility tree: Tracks, Filters, Engine, Transmission, Suspension, Brake System.

Though the M79 shot stock is an available module in the modifications, it can be at the bottom of prioritization as it currently possess no advantage over the stock M62 shell, having the same shell velocity but with worse penetration at all distances and angles, shallower ricochet angle, higher shell cost

Pros and cons

Pros:

• Powerful gun, stock shell can penetrate virtually any opponent it encounters, even the Tiger H1
• Good top speed for a SPG; allows it to get to positions timely
• The huge, V-shaped gun mantlet and gun breech can often bounce / absorb shells (eg. 75 mm M3 and 76 mm F-34 / ZIS-5)
• Good gun depression of -10° adapts almost all terrains
• Powerful roof-mounted M2 Browning can effectively damage light vehicles or low flying aircraft

Cons:

• Very poor turret traverse speed and sluggish hull traverse; not adequate results in close distance engagements
• Base armour is quite thin, easily penetrated by common opponents like the Pz.IV F2 or the US M10
• Open topped, vulnerable to aircraft strafing
• Only x3.5 gunsight zoom making it hard to shoot distant targets
• Poor reverse speed; affects the ability to retreat quickly
• Does not have access to Add-on Armor, more vulnerable to enemy fire as a result

History

Some years after the Second World War, in 1948. The Republic of China's party, Kuomintang, ordered the Armoured Forces Command to establish special groups of personnel dedicated to locating and acquiring surplus equipment or abandoned materials of war. These groups travelled to several places, including the Pacific theatre.

The groups managed to collect several M10 tank destroyers used by the Americans during battles in the Pacific. Other vehicles like the M5 Stuart and the amphibious LVT-2 also were collected. Most of these vehicles were only lightly damaged by combat. But the majority of their original 76 mm guns were either destroyed or not reliable for service.

By the end of 1948, another 34 M10 tank destroyers were purchased from the United States. These findings and acquisitions were then shipped to Shanghai Longhua Tank Plant in mainland China for restorations and modifications.

Around this time, the Chinese Civil War was still ongoing. The numerous battles were frequently won by the Communist Party of China's armoured forces; and their rising superiority in tank numbers. This lead to their eventual total control of mainland China and the retreat of the Kuomintang to Taiwan.

M10's modifications

Once the Longhua Tank Plant was re-established in Taiwan, in 1949, the modifications planned for these M10 tank destroyers continued. They intended to increase the firepower and armour of these vehicles since it was considered obsolete for post-war use. The modifications would provide artillery support against a possible communist disembark on the ROC's islands.

The original 76 mm gun was to be replaced by a Japanese Type 91 105 mm howitzer, turning the vehicle into self-propelled artillery piece. However, the old turret design did not provide sufficient space for the crew and the new gun, so modifications to the turret had to be executed. After successful trials of this modification, about another 18 were modified.

After the modifications finished, they participated in the 1950's New Year's military parade, and in national parades during 1952 and 1953.

It is uncertain if they took part in any battle before this, since the Chinese Communist Army never successfully invaded Republic of China's islands, the M10s had to be evacuated from the Battle of Shanghai, and their use during the battle in mainland China would have been severely limited due to a shortage of ammunition available.

M10s in ROC's service ultimately got decommissioned by the arrival of the US's M7 Priest through 1955-1957. Most of the M10 were scrapped or their modifications disassembled.
