As explained in the rifle section, both the Chinese and the NK began the Korean War with a large number of Japanese WWII weapons.
The Type 96 Shiki Kikanju and the 11 Shiki Kikanju both probably saw action in Korea, and were similar in effectiveness. They used rimmed cartridges,
which needed oiling because they had no primary extraction and, without oiling, the case could not easily be withdrawn from the chamber. They mounted
a 2.5 type optical scope to improve target recognition and hit probability at extended ranges, the same philosophy as used by the Germans during WWII
and which the US adopted in the 1990s. The reduced power 6.5mm cartridge was partly intended to reduce muzzle flash since the MG normally did not mount
a flash suppressor. By the end of WWII, Japan had designed a 7.7mm Type 99 light gun, far superior to these 6.5mm guns, but did
not manufacture many.
