Leatherneck is a military slang term for a member of the United States Marine Corps. The dress blue uniform still bears that stock collar today, while the service uniform's standing collar was changed to a rolled-flat type prior to World War II. Now accepted by Webster as a synonym for Marine, the term "Leatherneck" was derived from a leather stock once worn around the neck by both American and British Marines—and soldiers also. Beginning in 1798, "one stock of black leather and clasp" was issued to each U. S. Marine annually.
Your history lesson for today. My avatar is me placing the American Flag in the sand in Kuwait the day we took it back from Iraq.
