A in circle was accepted as a symbol of 3rd USA Army.
Now this symbol is used as sign by many people, who consider themselves as an anarchist and sympathize with anarchist ideas. A writer, philosopher and producer of BBC company Peter Marshall said, that this symbol has an idea (developed by Peter Kropotkin and other anarchic theorists) about "Anarchy is Order" ("Anarchie ist Ordnung" and so on). You see, it's like, A in letter O, which are first letter of those words Anarchy and Order.
