Admiral vs. Colonel: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on October 17, 2023
"Admiral" is a high-ranking naval officer, while "Colonel" is a senior military officer rank below a brigadier general in the Army or Air Force.
Key Differences
"Admiral" and "Colonel" both refer to ranks within a nation's military, but they belong to different branches and hierarchies. An "Admiral" is specifically associated with naval forces. Depending on the country's system, there can be different types of admirals, with a full admiral typically being the highest rank.
Conversely, "Colonel" is a rank that primarily exists within land-based armed forces, such as the Army, and in some countries, the Air Force. The rank of Colonel is usually below that of a Brigadier General or its equivalent but is above a Lieutenant Colonel.
The responsibilities of an "Admiral" would often involve command over fleets, naval bases, or significant naval operations. An Admiral's jurisdiction would be over the sea, while their authority would span multiple ships and even entire naval installations.
In contrast, a "Colonel" would commonly have command over a regiment or brigade in the Army. Their sphere of influence would be land-centric, overseeing troops, strategizing land campaigns, or even training military personnel.
