COMSUBIN uniforms Comando Raggruppamento Subacquei e Incursori Teseo Tesei is the Italian Navy's special forces unit, whose uniform has several authorized differences from the standard uniforms used in the Italian Navy. GOI The Operational Raider Group (; abbreviated as GOI) is part of the Italian special forces and is one of the two sections that form the COMSUBIN. The GOI have different uniforms, including a scuba diving one. After being transported in a submarine, they use diving in order to stealthily reach places while remaining undercover. Another characteristic of this uniform is the harness used for steep access and egress points above water. GOS The Operational Divers Group (, abbreviated as GOS) is a special unit that is deployed for conducting any interventions in depths (of the sea) that reach more than 1000 meters underwater. The uniform used is fully black, with transparent scuba glasses, a torch mounted on top of the helmet and two oxygen tanks attached to the back of the operator. Carabinieri In Italy, there are two main police forces. The regular state police, the Polizia, and the Carabinieri. The Carabinieri were part of the Italian Army until the early 2000s. Since then, they are considered as an independent part of the Italian Armed Forces. The first nine written rules about Tuscany uniforms for Carabinieri date back to 9 August 1814 and recite the first design of the uniforms. Design The uniform that the Gendarmerie wore in 1814 consisted of a turquoise fabric buttoned suit with a blue collar and padded gloves. Since 1822, some small changes have been made to the uniform. Officers and Warrant Officers had silver swords and sabers, both in a black leather scabbard, worn with the dress. At the beginning of the 20th Century, the rules of the dress code were reinforced because of World War I. Troops had three different types of uniforms: the Complete uniform, the Ordinary uniform, and the Effort uniform. The Carabinieri's uniform at that time was made of a green-grey cloth material, and was used by all soldiers. Ceremonial dress uniform For historical and ceremonial use, the Carabinieri uniform consists of a distinctive black uniform made of silver braids around the collar and cuffs, edges trimmed in scarlet and epaulettes in silver.
