What is the abbreviation for an E-3 in the Army?

The correct choice for the abbreviation of an E-3 in the Army is PFC, which stands for Private First Class. In the rank structure of the U.S. Army, E-3 is designated for soldiers who have progressed from Private (E-1) to Private Second Class (E-2) and then to Private First Class (E-3). This rank signifies a soldier's advancement in terms of experience and responsibilities within the Army. It is an important stepping stone towards further promotions and responsibilities in their military career.

The other options represent different ranks within the Army; SPC stands for Specialist (E-4), CPL is Corporal (also E-4), and SGT stands for Sergeant (E-5). Each of these ranks comes after the E-3 level and entails additional leadership responsibilities and expectations.
