This page is about the turret-mounted autocannon B-20E (20 mm). For other mounting positions, see B-20 (20 mm) (Family).

Description

Write an introduction to the article in 2-3 small paragraphs. Briefly tell us about the history of the development and combat using the weaponry and also about its features. Compile a list of air, ground, or naval vehicles that feature this weapon system in the game.

Vehicles equipped with this weapon

General info

Tell us about the tactical and technical characteristics of the cannon or machine gun.

Available ammunition

  • Default: FI-T · HEF
  • Armored targets: AP-I · FI-T · AP-I
  • Air targets: FI-T · HEF · HEF-I

Comparison with analogues

Give a comparative description of cannons/machine guns that have firepower equal to this weapon.

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:

  • High muzzle velocity and flat trajectory, comparable to some heavy machine guns
  • Good rate of fire
  • API round capable of penetrating roof armour of tanks like the StuG III and the Panzer IV

Cons:

  • Low damage against aircraft compared to 20 mm cannons of other nations

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: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.

See also

Links to the articles on the War Thunder Wiki that you think will be useful for the reader, for example:

  • reference to the article about the variant of the cannon/machine gun;
  • references to approximate analogues by other nations and research trees.

External links

Paste links to sources and external resources, such as:

  • topic on the official game forum;
  • other literature.
