Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat? If necessary use a visual template to indicate the most secure and weak zones of the armour.

Ammunition600 rounds

Belt capacity75 rounds

Reloadbasic crew → aces

9.1 → 7.0 s

Fire rate997 shots/min

Vertical guidance-7° / 83°

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.

Note:

• Ammunition is divided into 8 magazines of 75 rounds.

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:

• Fast 900+ rounds/min firerate allows it easily score hits with a burst on an aircraft's flight path
• Small profile makes it very easy to conceal itself
• High top speed of 90 km/h means great agility
• Lack of armour means conventional cannons will struggle to one-shot it if poorly aimed
• 75-round belt allows it to confidentally engage targets without worrying too much about reloading

Cons:

• The driving compartment can obstruct the autocannon's gun depression which might be sometimes fatal
• No armour protection, making it highly vulnerable to MG bullets, shrapnel, and even ramming from tanks and aircraft
• Is wheeled, meaning its mobility will be significantly worsened on bad road conditions
• Reverse speed of -13 km/h can be inadequate, especially when comparing to its counterpart R3 T20
• Gunsight is position far above the gun, which can be awkward to aim in simulator
• Complex appearance can make it hard to place bushes, decorators, and decals

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.
