Give the reader information about the characteristics of the main gun. Assess its effectiveness in a battle based on the reloading speed, ballistics and the power of shells. Do not forget about the flexibility of the fire, that is how quickly the cannon can be aimed at the target, open fire on it and aim at another enemy. Add a link to the main article on the gun: {{main|Name of the weapon}}. Describe in general terms the ammunition available for the main gun. Give advice on how to use them and how to fill the ammunition storage.

Notes:

• Ammo rack 7 is a ready rack, and takes priority in being filled at the beginning of the battle.
• Full reload speed will be realized as long as ammo exists in the ready rack. If the ready rack is empty, a penalty to reload speed will occur.
• Not firing when the gun is loaded will load ammo from racks 1-6 into rack 7, as long as there is ammo in racks 1-6. Firing will interrupt the loading of ready racks.

Additional armament

37 mm M3 cannon

Ammunition202 rounds

Some tanks are armed with several guns in one or more turrets. Evaluate the additional weaponry and give advice on its use. Describe the ammunition available for additional weaponry. Give advice on about how to use them and how to fill the ammunition storage. If there is no additional weaponry remove this subsection.

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

Pros:

• The 90 mm cannon has adequate penetration with the stock M77 shot
• Can unlock the M82 APHE shell for an added punch

• Has a reverse gearbox, good for quick repositioning
• -10 degrees of gun depression
• The 37 mm secondary cannon can be used to counter lightly armored vehicles
• Not one, two, but three 12.7 mm machine guns

Cons:

• Weak overall armor protection
• 6 crew members are enclosed rather tightly
• Long hull is easy to shoot at
• No external smoke launchers

History

Describe the history of the creation and combat usage of the vehicle in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: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></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

Media

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