Tank cannons
The 20 mm KwK30 is a German tank cannon. It was primarily as the main armament of the Pz.II C and the Pz.II C (DAK). The KwK30 also served as the basis for the 20 mm C/30L, which was used on the He 112 A-0. An improved version that had a higher rate of fire, the 20 mm KwK38, was mounted on the Pz.II F.

Give a comparative description of cannons/machine guns that have firepower equal to this weapon.
The high fire rate and excellent penetration of the Kwk30 allows enemy tanks to be killed quickly. However, a small magazine and a lengthy reload rate allows enemies to fire back and destroy you. 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:
Cons:
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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: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 />.
Excellent additions to the article would be video guides, screenshots from the game, and photos.
