England never had a standing army with professional officers and careerist corporals and sergeants. Privates and non-commissioned officers, such as corporals and sergeants, are addressed using their ranks. Companies had Sergeants, Furirs and Corporals in them. Corporals wore two chevrons, privates none. Experienced soldiers who have served as corporals and sergeants may take a shortened course. Their introduction allowed the rapid differentiation of sergeants and corporals from private soldiers. The battalion consists of approximately 50 officers and NCOs, and 150 privates and corporals. The released soldiers included the Sergeant Major, two corporals and two rangers. They usually commanded a section of twenty men with two corporals under him. Originally, the Royal Artillery had corporals, but not lance-corporals. The date of introduction of lance corporals to the British Army is unclear. Corporals and specialists are addressed by their rank. Master corporals have seniority among themselves in their order of seniority as corporals. October saw two launches of WAC Corporals with 1/3rd loads of propellants. Within the Italian Royal Army are the elite mountain military corporals called, the Alpini.
