France

A second-lieutenant is equivalent to a junior commissioned officer (the French army does not use the terms commissioned or non-commissioned). During classes at officer training schools such as Saint Cyr the cadets rise quickly through the non-commissioned ranks of private, corporal, sergeant and reach the rank of ''aspirant'' which is the first officer rank. After additional training at specialised schools they get the bar of second-lieutenant. The insignia consists of a metal-colored bar in accordance with the color of the ceremonial uniform buttons and hat symbol. For example, for the infantry, gold being the metal of the ceremonial dress buttons, the symbol on the béret being a golden grenade with two crossed rifles, and the symbol on the '' képi'' being a single golden grenade, therefore the insignia of a ''sous-lieutenant'' is a gold-colored bar. For cavalry or forest rangers (light infantry mobilised from the Water and Forests Corp), ceremonial dress buttons were silver, as was the hunting horn on the forest commissioned officer's ''képi'', therefore the insignia of a ''sous-lieutenant'' is a silver-colored bar.
