Corporal
Corporal is a military rank in use by the armed forces of many countries. It is also a police rank in some services. The rank is usually the lowest ranking non-commissioned officer. In some militaries, the rank of corporal nominally corresponds to commanding a section or squad of soldiers.
The word is a contraction from the medieval Italian phrase capo corporale (transl. head of a body [of soldiers]).
The rank of corporal, which falls between lance-corporal and sergeant is used by the British Army, Royal Marines, and Royal Air Force.
The badge of rank is a two-bar chevron (also known as "stripes", "tapes", or "hooks"). A corporal's role varies between regiments; but, in the standard infantry role, a corporal commands a section, with a lance-corporal as second-in-command (2ic). When the section is split into fire teams, they command one each. In the Royal Armoured Corps, a corporal commands an individual tank. Their duties therefore largely correspond to those of staff sergeants in the United States Army and corporals are often described as the "backbone" of the British Army.
A common nickname for a corporal is a "full screw"
