Comparison with analogues

Compared to its peers, the gun has an average muzzle velocity, average rate of fire, and above average horizontal targetting speed. Its biggest weakness is the lack of the dedicated AP shells, which makes the gun unsuitable to deal with any heavily armoured target, even some of the heavy cruisers, like the Admiral Hipper-class. Explosive filler of the HE shells is also below average. Where the gun shines, however, are its SAP shells. Having by far the largest explosive filler among its peers, it's able to deal an outstanding amount of damage. This is done by having a lower penetration than most of the other comparable shells, but it's still able to penetrate the majority of the light cruisers

Usage in battles

Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against notable opponents. Please don't write a "guide" - do not impose a single point of view, but give the reader food for thought.

Pros and cons

Pros:

• Exceptionally large explosive filler of the SAP shells
• Above average horizontal targetting speed

Cons:

• Lack of dedicated AP shells
• Below average explosive filler in the HE shells

History

Examine the history of the creation and combat usage of the weapon 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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: https://wiki.warthunder.com/(Weapon-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 />.

Media

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