The trench coat became an optional item of dress in the British Army, and was obtained by private purchase by officers and Warrant Officers Class I who were under no obligation to own them.
[3] No other ranks were permitted to wear them. Another optional item was the
British Warm, a wool coat similar to the greatcoat that was shorter in length, also worn by British officers and Warrant Officers Class I as an optional piece.
During the First
World War, the design of the trenchcoat was modified to include
shoulder straps and D-rings. The shoulder straps were for the attachment of epaulettes or other rank insignia; There is a popular myth that the D-ring was for the attachment of hand grenades. The ring was originally for map cases and swords or other equipment to the belt. This latter pattern was dubbed
"trench coat" by the soldiers in the front line. Many
veterans returning to civilian life kept the coats that became fashionable for both men and women.
During the
Second World War, officers of the
United Kingdom continued to use the trench coat on the battlefield in inclement weather. Other nations also developed trench coat style jackets, notably the United States and Soviet Union, and other armies of continental Europe such as
France,
Germany,
Holland,
Poland (and are often seen in war zone photographs in the 1939-40 era, even worn by troops on the attack), although as the war progressed, in the field shorter "field jackets" became more popular, including garments such as the
Denison smock used by
British commandos,
paratroopers, and
snipers and the
M1941/
M1943 field jackets used by the
US Army. These garments were shorter and more practical than the trench coat, and as such they allowed the wearer to be more mobile.
[4]A typical trench coat by this period was a ten-buttoned, double-breasted long coat made with tan, khaki, beige, or black fabric. Trench coats often have cuff straps on the
raglan sleeves,
shoulder strapsand a belt. The trench coat was typically worn as a
windbreaker or as a rain jacket, and not for protection from the cold in winter or snowy conditions.
