Which of the following ranks has three silver stars in line?

The rank that has three silver stars in line is the Lieutenant General. In the U.S. Air Force, a Lieutenant General's insignia consists of three silver stars arranged in a row. This visual representation distinguishes them clearly from other ranks within the military structure.

Brigadier General, for example, is represented by only one silver star, while Major General holds two silver stars. Colonel insignia consists of a silver eagle, which does not include stars at all. This hierarchical insignia system is crucial for identifying and understanding the ranks and their respective responsibilities within the military.
