NOTE: Changing the Su-34 from A/G to A/A makes your game lose the integrity check. But you can always remove the mod in a minute in order to gain it back.
This Mod works on most of the 4YA servers so you can enjoy it online
Su-34 can be air to air or air to ground, but it has to be either one or the other. You can't make it a proper multi-role.
Changelog from Roberts Original Mod:
Added Gunpods
Added ELINT Pod
Moved the Elint Pod over to middle Pylons so you can have an extra pylon for weaponry
Added aircraft gun
