I suspect that a lot of First World War experience influenced the content of that Wehrmacht infantry squad manual, particularly the emphasis upon riflemen in the squad supporting the machine gun, instead of the other way around.

During that war change happened so fast that the lengthy review and approval process for official publications couldn't keep pace with new innovations on the battlefield. Because of that the British army artillery began publishing unofficial bulletins on changes in artillery practices, and the "Field Artillery Notes" put out by Fort Sill is the continuation of a practice begun by us in emulation of the British during that war.

The old Sturmtruppen appelation adopted by Hitler and the Nazis in the 1930s was a reference to the specialized assault battalions formed by the German army during WW I. Back then they were considered to be cutting-edge and their influence on German line infantry units then was similar to how some practices of Airborne units in the U.S. Army migrated over to straight-leg outfits post-1945.
