What does the symbol "/" indicate in Marine Corps ranks and rates?

The symbol "/" in Marine Corps ranks and rates signifies that there are additional ranks within a particular category. This means that it shows a hierarchy or a series of ranks that fall under the specified division. For example, when you see a designation like "Lance Corporal/Cpl," it implies that the rank of Corporal includes the rank of Lance Corporal as a junior rank within that classification.

Understanding this hierarchy is crucial in the military structure, as it reflects the different levels of authority and responsibility attributable to various positions. Additionally, the symbol "/" helps to simplify the representation of ranks, making it easier to convey relationships between different levels of service members.
