I don't think so. At the height of imperial power in the 2nd century, the Roman regular
military numbered about 150,000 with 350,000 in the reserves out of a population of 65 million. That is 0.23% active and 0.77% total. Later the number of active duty troops rose and the population fell, with the fraction of actives approaching 0.5%. I recall from my college history courses the idea that in ancient times standing armies greater than about 0.5% in the ancient world were unsustainable in the long run.
During the Cold War the US easily maintained armed forces in excess of 1.5% of population and the Soviet Union had more. During WW II the number of men under arms in the belligerent nations was far higher than it had ever been before or since.
