Which famous Marine is often associated with the quote about valor being a virtue?

The quote about valor being a virtue is often attributed to "Chesty" Puller, a highly decorated Marine Corps officer known for his exceptional leadership and bravery during multiple conflicts, including World War II and the Korean War. Puller's reputation for valor and his embodiment of the Marine Corps ethos have made him an iconic figure within the service. He has become synonymous with the ideals of courage and dedication associated with the Marines.

While General MacArthur and Admiral Nimitz were prominent military leaders, they are not specifically linked to the valor quote in the context of Marine Corps culture. Sgt. John Basilone is celebrated for his bravery and heroism, particularly during the Battle of Guadalcanal, but Puller's name is more closely identified with the broader discussions of valor and virtue among Marines. Hence, Puller stands out as the correct association with that particular concept of valor in the Marine Corps.
