Came across these two close up stills  from film footage of the campaign in China, probably late 30s

 

One with Fur Hats is cool, here we see that these hats could be made with different fur, the nap and the color being different among them. The other, the face of a charging soldier in warmer weather is equally cool.

Not in China in  the 30s but on New Guinea, probably Salamaua–Lae March 1942. Believe this is a still from footage where some parts of it was shown on the old The World At War ITV (TV network) series  from England n the early 70s.

Here is another still from the footage.
