Tank/APC turret un-movable and continuous Coaxial Fire

[ADF-ARA-RAN-RAAF]

A problem when I am operating Tanks in Single Player is that the Turret cannot be moved, nor can I fire it. Everytime I fire the Coaxial Gun, the sound is being played in a continuous loop and only stops when I change positions. The Machine Gunner's 50 Cal also disappears when I switch to the Gunner's position (3), nothing of the 50 Cal can be seen. When I switch back to the driver's position and begin driving the vehicle, the turret bounces up and down.

Happens to all Tanks and APCs accept for the M1A1 Abrams and the Challenger 2 on some of my custom SP Maps

With the Turret being unmovable, you need to give it some time ~15 seconds before it may be used, the coaxial looping sound is normal sometimes when you fire it as the turret is warming up. Maybe you should take some time reading the manual.

Regarding the .50 cal disappearing, I have no idea how to help you with that.

No the OP is right you can't fire weapons in SP its same for me.

On the SP maps some vehicles are single seat as the AI often just jumps in and drives off with no gunner. Some vehicles are MP and require a warm up time before you can operate them, give it 30 seconds.
