The highest rank in the U.S. Army is typically the four-star **General** (often denoted as O-10).
Based on the information provided:
* **General (O-10):** This is generally considered the highest rank in the U.S. military structure for all services, including the Army, under normal circumstances. A four-star general holds significant command responsibilities.
* **General of the Army (Five-Star Rank):** A higher rank, the five-star General of the Army, was created during World War II. According to the reference, this rank was "meant to be reserved for wartime or exceptional circumstances." This rank is rarely held and is considered a temporary rank conferred by Congress. No officers currently hold this rank in active duty or retirement.
Therefore, while the five-star rank of General of the Army exists historically for specific situations, the four-star **General** is the highest rank commonly achieved and currently held in the U.S. Army.
Here's a simple breakdown:
* **Standard Highest Rank:** General (Four Stars, O-10)
* **Exceptional/Wartime Rank:** General of the Army (Five Stars)
Understanding the different levels of General ranks helps clarify the structure at the top of the Army command chain.
