What is marine corps pith helmet?

The Marine Corps pith helmet, also known as the "sun helmet," is a type of military headgear made of lightweight, breathable material designed to protect troops from the sun and heat in tropical and subtropical environments. It is made of a cork-like material covered in canvas or other durable fabric and has a wide brim to provide shade to the face and neck.

The Marine Corps pith helmet has been in use since the early 20th century and is often associated with the iconic image of Marines in World War II. It has also been worn in more recent conflicts, such as the Vietnam War.

The helmet is typically adorned with various insignia and decorations, such as unit crests and rank insignia. It is still used today by some Marine units for ceremonial purposes and as a symbol of tradition and heritage.
