What does the term "Leatherneck" refer to in Marine Corps history?

The term "Leatherneck" refers to the protective leather stock that Marines historically wore around their necks to guard against cuts from swords. This piece of gear was part of the Marine uniform in the 19th century, particularly during the time of the early U.S. Marine Corps, when swordsmanship was a significant part of a Marine's martial skills. As a result, it provided not only protection but also a distinctive component of the uniform that contributed to the identity and heritage of the Marine Corps. This historical context is crucial in understanding the nickname's origin and its lasting influence on Marine Corps culture. While the other options reference different aspects of Marine life and history, they do not capture the specific historical significance of the term "Leatherneck" as it relates to the protective gear.
