Description

DEFA CN90F1, also known as DEFA 921, is a French light gun designed for light vehicles. Operating on low pressure and being exceptionally lightweight by itself, it made the creation of AML-90 possible: gun was relatively easy to operate while also permitted the 5-tonne chassis to punch well above its weight.

The most troubling thing was the long range performance of the gun. Using low velocity ammunition and having rather inadequate fire control systems, the accuracy of the gun was far from perfect if not outright terrible. The Six-Day war and South African Border War, where the vehicles equipped with it were used confirmed it, as the AMLs were being constantly outranged while fighting M48s and even T-34-85s. The light chassis used to accommodate the gun was also not allowing to fire on the move out of fear of overstraining the suspension and transmission (apart from that, the gun was never equipped with stabiliser).

Nonetheless, in conflicts where it was used, it proved to be perfectly capable of destroying MBTs, especially when attacking in flanking manoeuvres.

General info

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

Available ammunition

Describe the shells that are available for the weapon and their features and purpose. If it concerns autocannons or machine guns, write about different ammo belts and what is inside (which types of shells).

Comparison with analogues

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

Usage in battles

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.

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: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