Black beret
Appearance
The black beret is the headgear worn by the British Army's Royal Tank Regiment and by all the Russian (and formerly Soviet) Naval infantry and some Russian Spetsnaz units, among others. It was also formerly worn by the U.S. Army Rangers, and is now worn by all United States Army troops without a different distinctive beret, the Rangers now wearing tan berets. It is traditionally associated with armoured or special forces troops.
The most famous wearer of the beret was Field Marshal Montgomery "Monty" who wore two badges on his one of which was that of the RTR.
The Norwegian Panserbataljonen (armour) and E-bataljonen (intelligence) also wear black berets and it is also used by Brazilian military police.
