Notes

1. Germany's allies, in total, provided a significant number of troops and material to the front. There were also numerous units under German command recruited in German-occupied Europe and sympathetic puppet or neutral states, including the Spanish Blue Division, the Legion of French Volunteers Against Bolshevism, and the 369th Croatian Infantry Regiment.
2. The Islamic Emirate of Afghanistan, which was headed by the Taliban and governed 90 percent of Afghanistan, officially declared their neutrality in the conflict, though several Taliban factions went on to fight on the side of the opposition nonetheless.[29]
