ABSTRACT:
A turret drive assembly fixedly secured to a turret causes rotation of the turret via rotation of an aiming wheel fixed to the turret drive assembly. The turret drive assembly comprises a drive mechanism which is operatively coupled to an aiming wheel and a first sprocket wheel so that rotation of the aiming wheel rotates the first sprocket wheel. Rotation of the first sprocket wheel rotates a second sprocket wheel which rotates a drive gear which is engaged with a fixed ring gear secured to a vehicle. Rotation of the drive gear, when engaged with the ring gear, rotates the turret. The drive gear and ring gear may be disengaged from one another and held in such a position.
