This Trainable Gun Mount sub-assembly is a moveable mount between the gun box and the base plate that allows for azimuth movement.

• A. Gun Box
• B. Breech Assembly
• C. Trainable Gun Mount
• D. Yoke

Answer: (D)

Azimuth movement is horizontal rotation, so the component that actually provides the left‑right aiming is the yoke. It sits between the gun box and the base plate and acts as the pivot, carrying the gun’s weight while allowing the gun box to rotate around a vertical axis. The trainable gun mount refers to the movable assembly as a whole, but the mechanism that enables the azimuth motion is the yoke. The gun box houses the gun, and the breech assembly is part of the loading system, not the movement.
