What nickname was given to Marines due to the leather collars they wore from 1775 to 1875?

The nickname "Leatherneck" refers to the distinctive leather collars worn by Marines from 1775 to 1875. These collars were designed to protect against sword cuts and were a prominent feature of the Marine uniform during that period. The term reflects the toughness and resilience of Marines, evoking an image of a soldier with a rigid, unyielding demeanor. This nickname has endured through the years and is commonly used to refer to Marines, serving as a symbol of their proud heritage and fighting spirit.

In contrast, the other terms have different origins and meanings within Marine Corps history. "Devil Dog" is a nickname that emerged during World War I, stemming from the tenacity displayed by Marines in battle. The "Blood Stripe" refers to the red stripe worn on the dress blues of non-commissioned officers and officers, symbolizing the blood shed by Marines in combat. "Semper Fidelis," or "Always Faithful," is the official motto of the Marine Corps, emphasizing loyalty and commitment. Each of these terms represents a unique aspect of Marine identity, but the specific connection to the leather collars is what makes "Leatherneck" the correct answer.
