US Special Forces 'Mess With The Best Die Like The Rest' Insignia Patch (? Date)
 
The first military patches were worn by British officers in the 19th century to denote officer rank. With the coming Industrial Revolution and cheaper access to fabrics and sewing machines, patches became a norm in many militaries. During World War I, military patches became commonplace for the United States Military. Many units sported unique patches related to where they came from in the states or their unit nicknames, and many of these original patches have become collector's items over time.
 
Mess with the Best Die like the Rest - the saying has its roots associated with the US Army Special Forces, commonly known as the Green Berets in the late 1960s. The special forces community adopted it in the 1970s, and by the 1980s it was in fairly common usage.
