Army Sergeant, an E-5, leads soldiers directly and leads teams and section. Army Sergeants are represented by three chevrons.
E-5 is the first at which enlisted soldiers are referred to as sergeant, and of all the grades of the NCO, this one, very possibly, has the greatest impact on the lower ranking soldiers. Privates, who are the basic manpower strength and grade of the Army, generally have sergeants as their first NCO leader. It is the grade sergeant that the privates will look to for example.
