                    The 30 mm MK 101 (Maschinenkanone 101) was a machine cannon 
                    designed and produced by 
Rheinmetall-Borsig 
                    in 1940. This weapon was extremely powerful and accurate, 
                    but on the downside, the 30 mm MK 101 was extremely heavy, 
                    and how the slow rate of fire. The 30 mm MK 101 was fed by 
                    a 10 round magazine (for early models) 30 round magazine for 
                    later models. The ammunition used was included high explosive 
                    rounds, tungsten armour piercing rounds, which could penetrate 
                    up to 75 mm of armour plate at a range of 300. The 30 mm MK 
                    101 was further developed by 
Rheinmetall-Borsig 
                    and an electrically fired version was developed. This was 
                    the 
30 mm MK 103 
                    
                    The 30 mm MK 101 (Maschinenkanone 101) machine gun was installed
