the AMX turret cannot be done in game code - no way to have high ROF and then someone have to go out and move rounds from the hull to the mag (assuming your enemy will let you!
). So a general overall rate is used, as if it was a normal turret. (Otherwise it could "machine gun" all the ammo in the casettes plus the hull storage in continuous fire).
There are no autoloaders in SP 1/2/3 based code, anyway.
Number of smoke rounds is not relevant as smoke is not a database ammo item (ie editable in Mobhack) - but a random number of rounds added to some classes by the internal game engine on creation a unit. (Which is why it is editable in the scenario editor as the unit is by then created from the template info).
