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".

General info

Survivability and armour

The armour on this tank destroyer is pitiful. However, if angled, the top part of the front hull can bounce non-apcr shells from 37 mm guns. There is a part of the transmission area where it is very well armored and can bounce even 75mm shells at an angle. However, never play this tank destroyer as a brawler, and take every bounced shot as a lucky break and another lease on life. This tank has access to add on armour, which can actually help a lot.

Due to its open top, aircraft are a major threat, as they can knock your whole tank out our incapacitate your entire turret crew. If an aircraft makes a pass on you but misses, retaliate with the top mounted machine gun. As it is a .50 cal, a few well placed shots (engine, pilot, fuel tanks i.e.) might just destroy it.

Armour Type:

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

Main armament

Main article: M7 (76 mm)

For your battle rating, and even at higher battle ratings, you have a great gun. It can penetrate basically everything it encounters, including the legendary KV-1's frontal armour (when not very angled) with your default shell. Its default shell also has great after penetration damage, with very few tanks able to survive your first shot. Even if they do they will most certainly be crippled, making an easy target for finishing off, or for teammates. Your gun has great range, and is easy to aim with gradual shell drop off. Your shell drop off is not a lot, and is easy to calculate and compensate for its reload time stock is just average, but not fast enough for urban combat.

Usage in battles

Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

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.


Describe the history of the creation and combat usage of the ground vehicle in more detail than in the introduction. If the historical reference turns out to be too big, take it to a separate article, taking a link to the article about the vehicle and adding a block "/ History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref>, as well as adding them at the end of the article. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === Encyclopedia Info ===, also if applicable).


Excellent additions to the article would be video guides, screenshots from the game, and photos.
