The Nambu Type 99 machine gun was probably the finest Japanese small arm in use that the Imperial Army would have had during WWII. However, it was adapted only in 1939, not issued en masse until 1942, and did not see combat until 1943, a fate very similar to Germany's MP/StG-44 assault rifle: too little- too late. The Nambu Type 99 was chambered in the 7.7x58mm rimless rifle round, the same as that used in the Type 99 bolt-action rifle, basically a rimless version of the .303 British for those of you familiar with rifle cartridges. The Nambu Type 99, like the earlier Type 96 had several unusual features for a light machine gun, including the ability to mount the arisaka rifle bayonet and a special 1x scope. The Type 99 featured a higher cyclic rate of fire at 850 rounds per minute, The Type 99 borrowed much internal design from the Czech ZB-26, doing away with the unreliable cartridge lublicating system. In the end, the Type 99 did not save Japan from final doom in 1945 and the guns were scattered all over southeast asia, seeing use in the Chinese civil war, Korean War and in Vietnam in limited quantities.
