Found this Gun Misplacement on the G45_G_Tiger, Destroyed Model.

Modification:
Gun_01
Turret_01

Ouch!
Let me try loading that..
Yep... Same thing here. Very strange. Ill have to have look the visual over for the turret and gun.

So strange.. I'm not seeing any thing wrong in the visual files.
I'll mess with it after I fix the other issues.

Sure, no rush 😄

This is why the gun is in the wrong spot... It gun_01 is literally in the wrong location. The vertices are of this model are not in the same location as all other models..
The only way to fix this is load the FBX in 3DS and translate the model.
I could add some hack code but that risks screwing up other models.
If you want me to do this for you, I can... Let me now.
This image shows that gun_01's model is not in the right location.

I used my PKG Explorer program to find and display the models.

OK.. Extract this in to the current res_mods.
It has the fix for the G45_G_Tiger crashed gun.
After.. Load the G_45_G_Tiger in tank exporter and export the FBX to place were you extracted all the other tanks.
This should fix that floating gun issue. If you need more help, let me know :)
