What items are on the button of the Alpha blouse?

The correct answer focuses on the components of the insignia found on the uniform of the United States Marine Corps, specifically the Alpha blouse. The button features the emblematic design of an Eagle, Anchor, and Thirteen Stars, which represents the Marine Corps heritage and commitment.

The Eagle symbolizes the United States, while the Anchor represents naval traditions and the Marine Corps' historical ties with the Navy. The Thirteen Stars denote the original thirteen colonies, signifying the founding of the nation and the Marine Corps itself. This combination clearly reflects the Marine Corps' identity, values, and rich history.

Other options do not correctly represent the traditional insignia elements associated with the Marine Corps uniform. Each of those alternatives contains symbols or combinations that are not used in the depiction on the Alpha blouse, making the choice of the Eagle, Anchor, and Thirteen Stars the accurate representation.
