Who was the General responsible for the adoption of the EGA?

The correct choice is based on the historical significance of General Jacob Zeilin, who was the 7th Commandant of the Marine Corps. He is recognized for designating the Eagle, Globe, and Anchor (EGA) as the official emblem of the Marine Corps in 1868. This decision was pivotal in establishing a symbol that encapsulates the Marine Corps' global responsibility and unique identity, representing the nation and its commitment to sea-based expeditionary warfare. The EGA remains a lasting emblem of the values and traditions upheld by the Marine Corps.

General John A. Lejeune's contributions are monumental in other contexts, such as his focus on enhancing Marine Corps training and organization, but he did not have a role in the adoption of the EGA. General William M. Wright and General Chester W. Nimitz, while notable figures in military history, are not associated with the creation of this emblem, further solidifying General Jacob Zeilin's unique position in this specific aspect of Marine Corps heritage.
