What nickname was given to Marines by German forces during World War I?

The nickname "Devil Dog" was given to Marines by German forces during World War I, specifically during the fierce fighting at the Battle of Belleau Wood. This term originated from the ferocity and determination displayed by the Marines in combat, which the Germans likened to that of a fierce fighting dog. The nickname reflects both respect and fear, illustrating how the Marines' tenacity and bravery in battle made a significant impression on their adversaries. Over time, "Devil Dog" has become a source of pride among Marines and symbolizes their reputation as formidable and resilient warriors.

The other nicknames, while associated with Marines, do not have the same historical context tied specifically to World War I. "Leatherneck" refers to the leather collars worn by Marines in the 19th century, "Boxer" does not have a well-defined connection to Marine history, and "Jarhead" is a more modern colloquial term referring to the Marine's high and tight haircut. These nicknames do not capture the same significance or origin as "Devil Dog" in the context of World War I.
