help with attached weapon(rotation)

[trojen100]

I know that i can attach a weapon to a car but my problem is how can i allow the attached weapon to rotate the same as the tank,i have been capable of attaching the weapon to a humvee but i cant figure out how to make it rotate when a player mounts it ,you don't have to tell me the code i want to figure it out but at least tell me if this is possible or not
