We usually stick to documents relating to a single specific weapon, but today we have an interesting report on a whole bunch of guns. Our friend Hrachya sent us a copy of a 1943 US War Department report on Japanese Infantry weapons. Instead of just discussing the usual rifles, pistols, and machine gun or two, this document is much more complete. It covers a whole range of grenades, land mines, mortars, AT and AA guns, and artillery pieces.
The illustration quality leaves something to be desired, but there is a lot of good information in this 257-page report for anyone interested in the standard armaments of the Japanese Army during World War II. You can download the manual below. Thanks, Hrachya!
