Probably the Philippine Guerillas had a habit of taking and wearing the uniform of dead Japanese soldiers they personally killed as a badge of Courage and Bravery. Of course the higher the rank of the dead Japanese soldier the greater the courage and bravery. After the US Forces landed back in the Philippines, they were ordered to remove the uniforms as they were being mistaken by the Allied Forces as Japanese. They were pretty brave S*B.s "American Guerilla in the Philippines" is an excellent read. I believe they even made a movie with Tyrone Power after WWII.
