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

Usage in battles

Air-To-Air combat

The Oerlikon is great at dealing with enemy aerial targets. It has great fire rate and muzzle velocity making hitting the enemy much easier.

Ground targets

Due to the decent penetration the Oerlikon offers with the API-T shell, it can be used to deal with lightly armoured AFV's and can penetrate the tops of enemy MBT's.

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

Summarise and briefly evaluate the weaponry in terms of its characteristics and combat effectiveness. Mark pros and cons as a list.

Pros:

• Great damage against aerial targets

• Good penetration values

• Great firerate

Cons:

• Usually hull mounted on a helicopter, making it hard to aim.

History

The history of the Oerlikon goes back to WW1, when an autocannon called the 20mm Becker was made. It saw some use on german fighters but mainly served as an anti air gun.

After the war the designs were given to many other companies, where it saw extensive modernization (almost doubling its muzzle velocity).

In WW2 the cannon and its variants saw use on many warplanes such as the Bf-110,A6M Zero and the Bf-109.

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: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