How can I reduce ramzer bone to insert it in the leg model?

You could use the Scale tool to make it, and Attach, for attachment to the leg model.
Maybe the best way to work with the mesh is as "Editable Poly", you have a large number of tutorials on Youtube.

Tell me one more thing, where is the plane of the forest which is applied to the texture map file?

I think so far nobody knows it. :roll: By the way, congratulations your progress in your animated soldiers. 8)
