摘要

The system for aiming a gun (1) on a mounting (2) which can rotate over a wide angle about an axis (G1) behind it comprises a sleeve (6b) around the gun barrel and a shield (6a) which surrounds it. A jack inside this positions the gun barrel to limit swinging about a second axis (G2) passing through the center of gravity of the gun and perpendicular to its longitudinal axis.
