Moving the ammo belts guide to the new forum. (Old: Complete Guide to Picking Ammo Belts (Updated May 2023) - Air Force Academy - War Thunder - Official Forum)
The list is ordered by nation of design. So as an example if you’re playing as Britain and you want to find the GAU-4 for your Phantom, it’s under the US.
Guns marked as “(turret only)” are available only as defensive armament/on turrets of bombers and/or attackers.
Hold CTRL then press F to search for the gun you want.
