Which rank is represented by two silver bars in the Marine Corps?

The correct answer is that the rank represented by two silver bars in the Marine Corps is First Lieutenant. In the Marine Corps, the rank of First Lieutenant is denoted by two silver bars, which signifies a second tier of the officer ranks following the rank of Second Lieutenant.

This representation is part of a structured rank insignia system where officers are identified by their rank visually, using silver bars, gold bars, or other insignia that denote their specific rank. In contrast, Captain, which is represented by two gold bars, falls after First Lieutenant. Major and Lieutenant Colonel have their own distinct insignias, with Major displaying a gold oak leaf and Lieutenant Colonel showcasing a silver oak leaf. Each rank has its unique identification, contributing to the disciplined hierarchy within the Marine Corps.
