Some Sicels may have borrowed the cuirass, kepis and greaves from the Greeks. Union Officers were generally issued kepis for fatigue use. All kepis display the anchor insignia of the Marines. The "dark blue" of officers' kepis is actually very similar to black. In 1914, most French soldiers wore their kepis to war. The Paraguayans mostly wore leather shakos, but senior officers were given kepis. Kepis with a slightly higher back were formerly worn by the Luxembourg Army until 1945. French customs officers ("douaniers") and the Gendarmerie still wear kepis for ceremonial duty. Officers, however, still wore kepis behind the lines.
