How many soldiers lived before world war 2?

Before World War II, the number of soldiers worldwide varied significantly depending on the country and its military structure. For instance, in 1939, major powers like Germany and the Soviet Union had millions of soldiers in their armed forces, with the U.S. military numbering around 334,000 active personnel. Overall, estimates suggest that several million soldiers were under arms globally before the war began, reflecting the military buildup and tensions of the late 1930s.
