Which rank corresponds to the O-5 classification?

The O-5 classification corresponds to the rank of Commander in the U.S. Coast Guard as well as in other branches of the U.S. Armed Forces. This rank is associated with significant leadership responsibilities, often involving command over a ship, air squadron, or a large operational unit. A Commander typically leads a variety of personnel while executing mission objectives and may also have a role in planning and administration at higher levels.

In contrast, the other ranks mentioned do not match the O-5 classification. Captain, which corresponds to the O-6 level, signifies a higher rank and greater authority than Commander. Admiral and Lieutenant Commander are also outside the O-5 category, with Admiral being a flag officer rank (O-7 and above) and Lieutenant Commander being an O-4 rank, just below Commander. Understanding these distinctions is crucial for comprehending the military hierarchy and the corresponding responsibilities that come with each rank.
