The Retarded Guns of Imperial Japan (Part 2)
Arisaka Type 99 Rifle
The Arisaka Type 99 rifle was a development of the earlier Type 38 carbine. The major difference between the rifles was a change from a 6.5mm cartridge to 7.7mm. This change necessitated an increase in both length (10") and weight (1.3 lbs) to offset the increased recoil. The Type 99 was not a bad rifle in itself, although the increased length was a hindrance in jungle fighting, and changing calibers in the middle of a war caused logistics problems.
Arisaka Type 99 Rifle:
What's unique about the Type 99 is the weird and useless features that were added to it. First there is a monopod:
Type 99 with monopod extended:
Unlike a bipod such as on a Galil or StG-58, this monopod was completely useless. Not only does the monopod not provide a stable rest, but the wire used was very long and flexible and it would have been impossible to hold a target with it. It was common practice among Japanese soldiers to remove and discard the monopod as soon as possible.
The other weird feature of the Type 99 was its sights. They were graduated out to 1500m, optimistic certainly but typical for its period, and they also included fold-down antiaircraft sights.
Type 99 AA sights:
If the 1500m setting on the sights is optimistic, the AA sights are wishful thinking. Needless to say there is no record of the rifle ever bringing down an Allied aircraft.
Nambu Type II Machine Pistol
Part of Kijiro Nambu's ongoing war on aesthetics, these machine pistols were intended to fill the need within the Imperial Japanese Army for a decent submachine gun and replace the hodgepodge of captured foreign subguns being used in the Navy.
Type IIA:
This design was tested in 1937 by the Army and was rejected due to numerous design flaws, although it was in fact procured by both Navy and Army units and used in the war in China.
Type IIB:
After failing to get the Type 100 SMG to work well enough, in 1944 the Army turned to Nambu in desperation. He resurrected the Type IIA design and made several changes, resulting in the Type IIB design which was purchased by the Army. The Type IIB design, designated "Bullpup" by allied forces, had a very unusual appearance mostly because its trigger was inside the body of the stock and because of its pronouncedly overhanging receiver. This was probably because it was made using extra Arisaka stock blanks.
