French (Russian: френч) was the designation of a particular type of military jacket or tunic in the Russian Empire and later in the Union of Soviet Socialist Republics (USSR). In the years immediately preceding the start of World War I, several new models of khaki-grey uniform jackets were adopted in Russia for service wear by Imperial Army officers. In most cases these were related to (and influenced by) the latest creations in the armies of France and the United Kingdom. These loose-fitting and practical garments received the collective designation french in tribute to the supreme commander of the British Expeditionary Force to France, field marshal John French.
