The Third Marine Division Patch

The 3rd Marine Division Shoulder Patch worn during World War II is in scarlet and gold, the official colors of the Marine Corps, and consists of a scarlet triangular shield with a narrow gold line near the outer edge.  In the center of the shield is a gold and black Caltrap, an ancient military instrument with four metal points so disposed that any three of them being on the ground the other projects upward, thereby impeding the progress of the enemy’s cavalry.  Literally:  Don’t step on me! Also the three visible points of the Caltrap represent the division number.  This insignia was authorized in August 1943. In 1947, the wearing of the unit shoulder patches by all Marine Corps units was discontinued.
