Comparison with analogues

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

Usage in battles

Against armour, the 37 mm cannon should be used to fire at the roof or sides of medium tanks and light tanks. Against heavy tanks, the 37 mm should be used to knock out the engine, tracks or other important modules as it would not have sufficient penetration.

Pros and cons

Pros:

  • HVAP-T shells have excellent penetration against armour

Cons:

  • Packs a small amount of ammo in all but the Bf 110 G-2 gun pod
  • HEF-T shell doesn't have as much effect as Minengeschoss from 30 mm
  • Too slow rate of fire to be practical in a dogfight

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: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