How Many Generals in US Military?
Ever wondered how many generals serve in the US military and what their roles entail? For veterans and military enthusiasts, understanding the hierarchy of generals across the armed forces provides valuable insight into the structures that command America’s military might.
This guide will walk you through the ranks of generals, compare generals to admirals, and break down how many generals exist in each branch of the US military. From 5-star generals to the more commonly seen 1-star generals, we’ll cover it all.
The Ranks of Generals
“General” is the highest form of rank in most branches of the US military. However, not all generals are created equal. Here’s a quick breakdown:
General of the Army or General of the Air Force (5-star rank) - This is an extremely rare rank and is awarded during major wartime. The last time these ranks were in use was in the 1940s and 1950s.
General (4-star rank) - This is the highest rank in active service during peacetime, typically commanding major operations or serving as a branch chief.
Lieutenant General (3-star rank) - Responsible for commanding corps-sized units or acting in high-level staff roles.
Major General (2-star rank) - Oversees division-level organizations or operational strategies.
Brigadier General (1-star rank) - Often serves in a deputy capacity or oversees brigade-level operations.
Each rank carries increasing levels of responsibility and leadership over specific formations or areas of focus. Before we answer the question, "How many generals in US military," let's explore the differences between admirals and generals.
Admiral vs General
While generals hold command roles in the Army, Air Force, Marines, and Space Force, admirals serve as their counterparts in the Navy and Coast Guard. Both roles are strategic and ensure the smooth coordination of military forces in large-scale operations. Admirals, like generals, also rise through 1-star to 4-star ranks, with the occasional 5-star admiral being equivalent to the 5-star generals of other branches.
Number of Generals Per Military Branch
There are several hundred generals or flag officers in the US military. The number fluctuates based on missions and troops numbers, but generally they remain the same over the course of presidential terms.
