General info

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

Available ammunition

The default belt is available for all planes equipped with the MG 81. Belts "Armoured targets" and "AP-T" are for defensive purposes while belts "Universal", "Tracers" and "Stealth" are for offensive purposes (Ju-88 A4 and Ju-87 D-5 only).

• Default: AP-T · Ball · Ball · AP-I · AI

The default round that all players start with. With a mix of AP-T, AP-I and AI rounds along regular bullets, its efficiency is severely limited as it does not focus on any role but rather tries to fulfill all of them in the same belt. It keeps damaging planes until 1,500 m distance.

• Armoured targets: AP · AP · AP · AP-T

This belt is for armoured targets due to the high content of armour-piercing rounds together with tracers to support your aim. Its damage potential drops severely beyond 500 m distance.

• AP-T: AP-I · AP-T · AP-I · AP-T

This belt combines the benefits of armour-piercing rounds with incendiary rounds. Its damage potential drops severely beyond 1,000 m distance.

• Universal: AP-T · AP · AI · AP-I

This belt is the best to attack both air and ground targets. It keeps damaging planes until 1,500 m distance.

• Tracers: AP-T

This belt is uniquely composed of armour-piercing tracer shells. Its damage potential drops severely beyond 5,00 m distance.

• Stealth: AI · AP · AP · AP · AI

This belt combines the benefits of armour-piercing rounds with incendiary rounds while packing no tracers to prevent from revealing your position. It keeps damaging planes until 1,500 m distance.

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: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