Abstract: The military equipment comprises a turret mounted for rotation about a vertical axis and supporting, by means of a swivelling device with horizontal axis, a main heavy gun totally external to the turret, having its own shield and situated approximately in a plane passing through the axis of rotation of the turret. The swivelling device comprises two lateral supports surrounding the gun and supporting the latter via bearings so as to define an elevation axis situated behind the rotational axis of the turret. One of the supports and the shield of the gun have oppositely situated openings for forming a protected channel for a gun loading system supplying the gun with rounds of ammunition from inside the turret. The feed system constitutes a unitary assembly. It has a frame secured in the gun shield on which a carriage is transversely movable between a position where an ammunition craddle supported by the carriage is aligned with a weapon and a position lateral to the weapon.
