Distinctive Patches of the Office of President of the United States
There are many support agencies dedicated to the office of president of the United States. The Secret Service use the coat-of-arms of the president on its uniformed officers, the White House Food Service workers have its own patch featuring the coat-of-arms of the president as well as the military personnel assigned to Air Force One, the helicopter Marine One and even the Washington, DC District Police use the coat-of-arms on its motorcycle presidential escort division.
Naturally, there are also many patches that were produced commercially that are not official. A few are designated here as well.
Many of these distinctive patches are shown here, but I’m sure there are others. Please drop a photo and description here, even if it is used unofficially.
