What symbol is featured on the buttons of the service coat?

The symbol featured on the buttons of the service coat is the Hap Arnold Seal. This seal, named after General Henry H. Arnold, is significant because it represents the lineage and heritage of the United States Air Force. The presence of the Hap Arnold Seal on the buttons serves to promote pride in service and a connection to the history of the Air Force.

The other symbols mentioned, while important in their own rights, do not appear on the buttons of the service coat. The National Seal is used in various official government contexts, the Air Force Crest represents the overall branch of the military, and the Star and Stripes symbolize the nation itself. However, none of these symbols hold the specific significance linked to the Hap Arnold Seal as it pertains to the service coat's buttons.
