Information Summary #01
January 1944
The model 1943 carbine-machinegun is designed to be used by infantry divisions that fight in forests. Two divisions in the Volkov and Holmsk directions had these weapons. Submachineguns have proven to be ineffective in the forest due to poor penetration. Machineguns are too heavy and not maneuverable enough. It is hard to aim and see when firing from the ground, and uncomfortable to fire from trees. machinegun-carbine combines the maneuverability of a submachinegun with the penetration of a machinegun. The system is well balanced and mobile. Firing in bursts has very light recoil. It is light and comfortable to use. One drawback is that it uses a special round with a shortened casing. Despite that, it has the penetration of a rifle at 400 meters. The magazines (30 round capacity, 7 are carried by each rifleman) are comfortable to use.
The weapon is gas-operated, tilting bolt. The effective range is 100-800 meters. Rate of fire: 500 rounds per minute."
