GarageImage M10 GMC (France).jpg

The ▄3-inch Gun Motor Carriage M10 (▄M10 GMC) is a Rank II French tank destroyer with a battle rating of 3.7 (AB/RB) and 3.3 (SB). It was introduced in Update 1.75 "La Résistance".

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.

General info

Survivability and armour

The armour of the M10 GMC is essencially decent for the rank, and with proper angling is able to ricochet a lot of shells, however, the armour is not thick enough to resist any of the stronger tank weapons of Rank II and above. The sides and back are quite thin and are not able to resist most weapons stronger than a 12.7 machine gun. 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 fragmentation, leaving the crew untouched, allowing for a retreat and repair without crew losses. The turret's top is open and because it that it is quite vanurable to HE shells and planes, being able to survive artillery barrages that fall nearby due to the fact that the crew is protected by the angled sides of the turret.

Armour Type:

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

  • 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 gives 20 mm of extra armour.

The M10 GMC has essencially the same mobility features as the M4 Sherman tank. When spaded, the tank is able to more quite fast in a straight line, going slightly below or even up to it's max speed. The turning speed is not that great and the reverse speed does not have much going for it either. The tank struggles while driving on inclines due to it's narrow tracks. In conclusion, the mobility of the M10 GMC is moderate and it is able to reach wanted positions reasonably fast.


Main armament

Main article: M7 (76 mm)

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. Because APCBC has enough penetration, the AP ammo is less useful. 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 it's 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.

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.

The best way to survive combat situations is to find a hull down location. The M10 has enough gun depression to use many hull down locations, and it has a strong enough turret front and mantlet to consistently cause ricochets. From there, well aimed shots should be able to knock out most enemy tanks at the battle-rating range from long range.

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, 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.

Pros and cons


  • Main cannon penetration and damage is very good for the rank, can knock out many tanks in one hit.
  • Good gun depression of -10°, perfect for hull-down positions.
  • Front armour profile can resist certain shots, with front glacis steeply sloped and the gun mantlet thick enough to absorb shots
  • 5 crew members to replace 3 incapacitated crew members, plus one more with Crew Replenishment modification.
  • Turreted purpose-built tank destroyer allows for wide field of fire compared to casemate designs.
  • Pintle mounted HMG can offer effective anti-aircraft fire.
  • Access to modification "Add-on Armour", that actually helps a lot.
  • Has relatively no problem when getting uptiered.


  • One of the slowest turret traverse in the game.
  • 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, leaving the vehicle is vulnerable when targeted by aerial attacks such as artillery or planes
  • Below average reverse speed
