Ground crew pt.1
This part will not be about "equipment & stuff" but about the Japanese Army ground maintenance crew, their uniform and various poses often seen in photos (but rarely seen in dioramas).
The early uniforms of the ground crew were usually 2-piece, white, always with puttees. There were two kinds of uniforms worn during the Pacific War in the Japanese mainland, the most common was the "type 2". It was an one-piece, with a cloth belt and cloth straps on the legs but buttons on the torso and sleeves. Below are the official drawing and photos I found here (the guy is selling an original uniform) and here, with excellent explanation and details of this replica.
There were two kinds of field caps. The first is shown below.
The second kind started as a side cap in the early '30s but received a brim and started as "Type Otsu" in 1934, an experimental in 1936 with two holes on the side and the standard "simplified" in 1938 with three holes on the side. They were of many different shapes and with use the same kind of caps look completely different.
The maintenance crew wore at least two kinds of footwear. Very common were the "jika tabi" with or without split-toe but also the classic Army short boots and their variations made from pig, cow, horse or even shark skin. The soldier tied the bottom of his one-piece uniform, stuck them inside his white socks and tied the boots with the laces. Puttees were very rare for the ground crews except perhaps in the "Koku Shikan Gakko" (Army Officer's Academy) where things were more strict.
Again, this uniform was mostly worn at the airfields in mainland Japan, the Japanese collonies at the time (Korea, Taiwan), in Manchuria and occasionally in China depending on the unit and the location. As you can see in the photos the uniform became easily very dirty and the soldiers often unbuttoned the top and wraped it around their weist when the day was too hot leaving themselves half-naked or wearing undershirts. In the photos below note the different jika tabi, the Army boots and the different kinds of caps.
Note that the guy above is holding the drop tank attachment of a Nakajima Ki-44 "Shoki".
