Description

The GIAT Industries 20 mm F2 (otherwise known as M693) is a dual feed autocannon which fires the standard 20x139 mm munitions. It is a gas operated autocannon that has three firing modes, those being single shot, burst and safe. The gas system of the weapon operates via two vents on either side of the barrel, through which the gases push against the two pistons. While firing, the two pistons are pushed back, moving the struts backwards so that the breech block can move to the rear. In this way, all the firing forces are developed along the barrel centerline which maximizes accuracy.

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: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

An excellent addition to the article would be a video guide, as well as screenshots from the game and photos.
