Which US military branch is the largest in size?

This has been bugging me, and I didn't really find an answer online. Tech-wise, personnel-wise and/or geography-wise, which branch of the United States military is considered the 'biggest'? Just trying to get a sense of the scale. Thanks in advance!

In terms of active-duty personnel, the United States Army is the largest branch of the U.S military. As of 2023, there were approximately 450,000 active-duty personnel serving in the Army.

When looking at each branch’s total number of personnel, which includes both active duty and reserve components, the Army still comes out on top with over 1 million soldiers in total.

Geographically speaking, the size and dispersion of military bases can be hard to pin down since the U.S military assets are spread throughout the country and around the globe. However, the U.S Air Force manages the largest number of bases worldwide, presumably due to the nature of their operations.

In terms of technology and equipment, comparing scale can be difficult because each branch operates different types of equipment suited to their specific domains. However, if you consider the Navy's fleet of aircraft carriers—which are effectively floating cities capable of projecting power across the globe—it could be argued that the Navy operates some of the "largest" technology in the U.S military.

Each branch plays a crucial role in meeting the overall defense objectives of the U.S, and size is just one aspect to consider when looking at the breadth and depth of U.S military strength.
