so as to distinguish themselves from having anything to do with Imperial Russia. Hungary had nearly the same symbol, while Romania had a different one. The Deutsche Luftstreitkräfte, or East German Air Force, used a particularly modernistic vol as its cap badge. This had extra significance, because the Luftwaffe of Nazi Germany used an eagle carrying a swastika. Currently, the Russians have returned to their heraldic past, while the Germans use a symbol different from that of the Luftwaffe. Insignia of branch of service Air services which are not independent from their country's armies have used a vol as the insignia of their branch of service. The US Army Air Forces, during the Second World War, used a winged, two-bladed propeller on the lapels of their tunics. The same sort of insigne was used by the Soviets before they had an independent air force. Warsaw Pact armed forces often had a red, five-pointed star superimposed upon the juncture point of this symbol. Pilot's insigne It is as the symbol of "wings" given to trained aircraft operators for which the vol is primarily used. All of the pilot's badges of the USAF, as well as the various Naval Aviator's badges of the USN, employ vols with a shield standing for Congress in the middle. These are of different design, and the USAF used silver while the USN uses gold, and has an anchor behind the shield. The US Army uses "wings" with an open parachute in the middle for paratroopers. During the Second World War, the uniforms of Denmark, Norway, Belgium, France, Nationalist China, and even the RAF used a form of the vol as their pilot's insigne. The air forces of Belgium, the Netherlands, Italy, Greece, Poland, and Yugoslavia used an entire bird. The Japanese had quite a different emblem; its wings are recognisably those of an aircraft. Rank insigne For the Luftwaffe, a vol was used to replace the chevron on the sleeves of enlisted men's uniforms. And the Romanian Air Force before 1945 used a vol for the shoulder rank insignia for warrant officers.

Collar tab insigne The uniforms of British Army officers have "gorget patches" of a color different from the rest of the uniform sewn on their lapels, and so did many arms of the German military. Specifically, the uniforms of both enlisted
