what is the role of a corporal in the army
Corporal In some militaries, the rank of corporal nominally corresponds to commanding a section or squad of soldiers. However, in the United States Army, the rank of corporal is considered a "lateral promotion" from E-4 Specialist and usually only occurs when the soldier has been selected by a promotion board to become an E-5 Sergeant and is serving in an E-5 billet such as a fireteam leader in a rifle squad. The lateral promotion is used to make the soldier a non-commissioned officer without changing the soldier's pay. As the Table of Organization & Equipment (TO&E) rank of a fire team leader is sergeant and that of squad leader is staff sergeant. In the United States Marine Corps, corporal is the Table of Organization (TO) rank for a rifle fire team leader, machine gun team leader, light mortar squad leader, and assault weapon squad leader, as well as gunner on most larger crew served weapons (i.e. medium mortars, heavy machine guns, and anti-tank missiles), armored vehicles (e.g. tanks, light armored vehicles, and armored assault vehicles), and the two assistant gunners on a howitzer (the gunner is a sergeant).
Joint Chiefs of Staff The Chairman of the Joint Chiefs of Staff is, by law, the highest-ranking military officer of the United States Armed Forces,[20] and the principal military adviser to the President of the United States. He leads the meetings and coordinates the efforts of the Joint Chiefs of Staff, comprising the chairman, the Vice Chairman of the Joint Chiefs of Staff, the Chief of Staff of the United States Army, the Commandant of the United States Marine Corps, the Chief of Naval Operations, the Chief of Staff of the United States Air Force, and the Chief of the National Guard Bureau. The Joint Chiefs of Staff have offices in The Pentagon. The chairman outranks all respective heads of each service branch,[21] but does not have command authority over them, their service branches or the Unified Combatant Commands.[21] All combatant commanders receive operational orders directly from the Secretary of Defense.[22]
