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.

The KwK38 (20 mm) was an improved version of the KwK30 (20mm), having almost double the fire rate than its predecessor. It is used on the later version of the Panzer II - the Pz.IIF.

Comparison with analogues

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

Usage in battles

The extremely high fire rate and excellent penetration of the KwK38 allows enemy tanks to be killed quickly. Try not to "spray-n-pray", as you will quickly use up all your ammo, and allow enemies to fire back and destroy you during your long reload time. After shooting at enemies, take cover to reload. Try to avoid long-range engagements, as the penetration rate drops off rapidly at around 500 m.

Pros and cons

Pros:

  • Extremely high fire rate
  • High penetration at close/medium ranges when using PzGr 40 belt with HVAP-T
  • Better fire rate and penetration when compared to other 20mm cannons at its rank

Cons:

  • Relatively long reload of 7.8 seconds when stock
  • Small magazine, only has 10 shells
  • Because of the high fire rate and small magazine, it is easy to waste all your ammo in a few seconds.
  • Penetration rates drop off sharply around 500m

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: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

An excellent addition to the article would be a video guide, as well as 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.

Paste links to sources and external resources, such as:

  • topic on the official game forum;
  • encyclopedia page on the weapon;
  • other literature.
