and other branches the sword was usually left with non-essential baggage when units reached the front line. It was not until the late 1920s and early 1930s that this historic weapon was finally discarded for all but ceremonial purposes by most remaining horse mounted regiments of Europe and the Americas. In China troops used the long anti-cavalry Miao dao well into the Second Sino-Japanese War. The last units of British heavy cavalry switched to using armoured vehicles as late as 1938. Swords and other dedicated melee weapons were used occasionally by many countries during World War II, but typically as a secondary weapon as they were outclassed by coexisting firearms. A notable exception was the Imperial Japanese Army where, for cultural reasons, all officers and warrant officers carried the Type 94 shin-gunto ("new military sword") into battle from 1934 until 1945. Ceremonial use Swords are commonly worn as a ceremonial item by officers in many military and naval services throughout the world. Occasions to wear swords include any event in dress uniforms where the rank-and-file carry arms: parades, reviews, courts-martial, tattoos, and changes of command. They are also commonly worn for officers' weddings, and when wearing dress uniforms to church—although they are rarely actually worn in the church itself. In the British forces they are also worn for any appearance at Court. In the United States, every Naval officer at or above the rank of Lieutenant Commander is required to own a sword, which can be prescribed for any formal outdoor ceremonial occasion; they are normally worn for changes of command and parades. For some Navy parades, cutlasses are issued to Petty Officers and Chief Petty Officers. In the U.S. Marine Corps every officer must own a sword, which is prescribed for formal parades and other ceremonies where dress uniforms are worn and the rank-and-file are under arms. On these occasions depending on their billet, Marine Non-Commissioned Officers (E-4 and above) may also be required to carry swords, which have hilts of a pattern similar to U.S. Naval officers' swords but are actually sabres. The USMC Model 1859 NCO Sword is the longest continuously issued edged weapon in the U.S. inventory The Marine officer swords are of the Mameluke pattern which was adopted in 1825 in recognition of the Marines' key role in the capture of the Tripolitan city of Derna during the First Barbary War.
