What rank corresponds with a collar device displaying four silver 5 pointed stars?

The rank that corresponds with a collar device displaying four silver five-pointed stars is General. In the U.S. Armed Forces, particularly the Army, Air Force, and Marine Corps, the insignia of a General consists of four stars, which represents the highest rank within that echelon. A General is a four-star officer, with responsibilities that typically include overseeing large military operations, providing strategic direction, and leading entire organizations or branches.

The insignia's design, featuring four stars, distinctly identifies the rank as General rather than any other rank associated with fewer stars. For example, a Major General has a one-star insignia, while a Lieutenant General has three stars, and Admiral, though it carries a four-star insignia in the Navy, typically refers to a different branch of service. In the context of Army, Air Force, and Marine Corps ranks, the four-star insignia unequivocally signifies the rank of General.
