Beret
ommonwealth. Berets have become the default military headdress of the late 20th and early 21st centuries, just as the tricorne, shako, kepi and peaked cap were in various early eras. The beret is now worn by elements of the military personnel of the majority of nations across the world. The three major hold-outs were the United States, Russia, and China (PRC) - all have now followed the example of the other armies in adopting berets.
