Ammunition is to be supplied to.

(Problems to be Solved by the Invention) In recent years, it has been demanded that the caliber of the gun body of the machine gun be enlarged. However, as the caliber of the gun body became larger, the ammunition box became larger, and in particular, the ammunition box became longer in the longitudinal direction and the height became higher. When equipped on a ship,
Although there are relatively few problems, when it is mounted on a vehicle, there are problems such as a hindrance to the height limitation of the vehicle and an increase in the position of the center of gravity, resulting in a decrease in running stability.

Since the large-calibre machine gun is a weapon with excellent combat ability and is indispensable for improving land combat ability, we changed the arrangement of the ammunition box and swung the ammunition box of the gun body. There is a demand for a structure that can be transported on land by fixing it at a position different from the shaft to reduce the size below the gun rack, thereby reducing the overall height.

The present invention has been made in view of the above-mentioned conventional circumstances, and an object thereof is to provide a fixed ammunition box type cannon that is low in height and can be transported on land.

(Means for Solving the Problems) The present invention is provided with a base, a gun main body provided on the base so as to be capable of swiveling and elevating, and provided coaxially with a turning shaft of the gun main body.
