There are several ranks of sergeants. Buck sergeants (three chevrons) and staff sergeants (three chevrons with one rocker) led squads, usually of about twelve men. A platoon had four squads. There was a platoon sergeant (three chevrons, two rockers), the top enlisted man in a platoon. The platoon commander was supposed to be an officer, a second lieutenant or a first lieutenant. Platoon leaders got killed a lot. Platoon leader was the single most lethal job of the war. When the lieutenant went down the platoon sergeant took over, until a new lieutenant was assigned. So, squad leaders reported to either the platoon sergeant or the platoon commander, and the platoon sergeant reported to the platoon commander, unless he had become the platoon commander. If the platoon sergeant was leading the platoon he met with the captain or the first lieutenant commanding the company, with the other platoon commanders, when officers were called to company HQ to discuss plans or receive orders.
There are several grades of Sergeant.. there's Sergeant, Staff Sergeant, Sergeant First Class (Army), Gunnery Sergeant (Marine Corps), etc..
A basic Sergeant is typically responsible for leading a fire team (four persons, including themselves). I've seen a lot of Marine Corps Squad leaders who've held the rank of Sergeant, though, and some in the Army (although they were usually eligible for promotion to Staff Sergeant).
The First Sergeant would be responsible for implementing it at the company level, but the program itself goes well beyond company level.
The first sergeant...............
There's a few different positions for a Sergeant Major. A Command Sergeant Major will be the senior noncommissioned officer of a Battalion or larger sized element, while a Sergeant Major will typically be in a staff position, and may serve as the senior NCO of that staff. They are primarily responsible for the noncomissioned officers under them.
Company Quartermaster Sergeant (CQMS) holds the rank of Colour Sergeant (C/SGT) or Staff Sergeant (S/SGT) and is responsible for the management of materiel (The equipment, apparatus, and supplies of a military force) at company level.
The life blood of a US Army company is the squad leader, regardless of rank. The typical rank for a squad leader is Staff Sergeant (E-6). The squad leader is responsible for the training and care of all soldiers in the squad. While the platoon sergeant, first sergeant, platoon leader, and company commander all play important roles, the person who is responsible to ensure the work gets done is the squad leader.
A platoon sergeant is someone who is responsible for the care and well-being of a platoon of soldiers. It is a description of a job. A Sergeant First Class is a pay grade (rank). It is also called E-7, and abbreviated SFC. Usually (but not always) the job of platoon sergeant is given to a soldier in the pay grade of Sergeant First Class, due to their experience and skill. It is possible to have a well-performing soldier of the previous rank (Staff Sergeant) doing the job of platoon sergeant, and it is also possible that a Sergeant First Class could be doing something other than leading a platoon (staff duty, for example).

There is no such rank as "First Class Sergeant". You have either Sergeant First Class, which is E7, or First Sergeant, which, along with Master Sergeant, is E8.
