Sometimes it seems the military is one big blended branch with everyone doing similar jobs. Marines have distinctive uniforms that are unlike how any other branch dresses. Sometimes Marines may be confused with Army soldiers, especially in combat when uniforms look similar. 

Here are a few key differences to help you spot a Marine a mile away:

  1. Marines don’t wear berets
  2. Marines may only wear boots with utility uniforms 
  3. Marines can only salute when wearing a cover 
  4. Marines only wear covers indoors when they are “under arms”
  5. If a Marine is wearing their utility uniform you can find their rank on the collar.

Fun Marine Corps History Fact: The nickname Leatherneck originated from a leather collar, called The Stock, which protected Marines’ necks during combat. The Stock was part of the Marines’s uniform from 1798 to 1872.

Even as the U.S. military’s smallest branch, the Marine Corps is made up of a tight-knit group of individuals who uphold the phrase “Semper Fi” — meaning “always faithful” — in all that they do. 

Marines are known to fight to win whether they’re on the ground, in the air, or sailing the sea. Not everyone is cut out to be a Marine, but the ones who do their jobs with accuracy, pride, and integrity. 

As the saying goes, the Marines are “The Few. The Proud.”
