‘Written by the U.S. Army Training And Doctrine Command in 2009, this 60-odd page document PDF was designed to function, in the words of its creators, as “a hip pocket” reference book for soldiers in the field. Categorized by geography, it groups the logos and insignia of “insurgents, terrorists, paramilitary, and other militant groups worldwide.” That includes everything from photos of Russian mafia tattoos to Hezbollah logos, as well as a thorough auxiliary list of branding from the “media wings” of each group.’ (Gizmodo).
