How many good conduct years do two hash marks represent?

Two hash marks on a service ribbon indicate a total of four years of good conduct in the military. Each hash mark represents two years of satisfactory service, specifically in terms of conduct and performance. Therefore, when a service member has earned two hash marks, it reflects a commitment to maintaining exemplary behavior and performance over the course of four years. This is an important recognition within the military, as good conduct is considered a significant aspect of service that contributes to unit cohesion and operational effectiveness.
