Military beret
Berets are also used by the Finnish Border Guard, which is a military organization under the aegis of Ministry of Interior during peacetime.The military beret originated in the French Army, in the form of the wide and floppy headdress worn by the Chasseurs Alpins (mountain light infantry) from their foundation in the early 1880s. The practical uses of the beret were soon known army-wide: the entire Expeditionary Force sent in China in 1900 used berets as headwear A tight-fitting version was subsequently adopted by French armoured troops towards the end of World War I. Between the wars, special fortress units raised to garrison the Maginot Line wore khaki berets as did the 13th Demi-Brigade of Foreign Legion when it was created in 1940. The Vichy Milice of the War period wore a blue beret.
